I found this while working on T274551, which is all about the
definition of "empty".
In the old sidebar a parameter's name is dimmed (gray) as long as
the parameter's value is empty. This stops working entirely when
there is a default value.
My first impulse was "this is a bug". When there is a default
value, both the empty string and the default value (when the user
enters it exactly) typically trigger the same behavior: The
template uses the default value, just as if the user entered it.
But this code is correct because of the way it is used. Only
parameters that are "truly" empty should be visually marked as
such. The moment there is a default value it is either impossible
to change this back to an empty string – meaning the parameter
can never be truly empty – or the empty string is meaningful user
input.

This should not have any effect on how the thing looks and
behaves.
* All elements in the sidebar should be reachable with the tab
key, including disabled elements.
* Enter jumps to the corresponding paremeter in the content
area on the right. But enter doesn't change the checkbox
state.
* Space canges the checkbox.
The class will be renamed in the next patch.

As discussed in Ia44da16. This change avoids possibly hundreds
of events (when a template does have hundreds of parameters),
and replaces them with a single one.

There is still a lot to do, but this implements some basic
behavior that was missing before.
* You can now use the tab key to navigate all checkboxes,
including disabled ones (required parameters).
* Enter key now works on both the checkbox as well as when
the entire line is highlighted. Enter forces the checkbox
to be checked and moves the focus to the content area.
* Mouse clicks now work on the entire line. Before, only the
text label was clickable.
Open issues (not to be resolved in this patch):
* Clicking the text label and the empty space after the text
label does different things. Probably shouldn't.
* Should a click on the label check the checkbox?
* Space key should probably not move the focus to the content
area.
* Focus rectangle is different on disabled rows. Is this ok?
* Background color when a line is focussed is missing.

The checkbox is the first parameter in the parent constructor.
The parent is the FieldLayout class. The checkbox becomes the
this.fieldWidget in the parent class. Just use this instead of
storing a duplicate reference.

I get a scrollbar at the bottom of the sidebar. The reason is
that the container's width is 100% + 1px. The extra pixel is
from the border, which is not needed in this mode.

This check makes sure the user doesn't loose work when clicking
the back button. I would like to argue that neither of these
values is valuable enough to block the user with a confirmation
dialog:
* Literally nothing is lost when the input is empty.
* The auto-value is only temporarily lost, but will
automatically be restored when the user decides to add the
template back. The input field is pre-filled with this value.
* The default value doesn't need to be manually entered. It will
show up anyway when the parameter is missing.
There is a rare edge-case, but it is not really relevant in this
situation. Some templates allow to override a default value with
the empty string. This will be considered irrelevant by this
code. However, this was already happening before and doesn't
change with this patch.
The only edge-case where this patch makes a difference is if a
parameter is marked as required or suggested, is documented to
have a default value, _and_ the template allows to override it
with an empty string. But this combination is rather crazy, if
not bogus, and not worth considering here, I believe.

This is really only about the methods name, but doesn't change
any behavior.
I realized we work with several different definitions of what
"empty" means. There are at least two significant definitions:
1. When a parameter's value is the empty string or identical
to the default value, the behavior of the template is the same.
It will use the default value just as if the user entered it.
The auto-value is a meaningful value in this scenario and can't
be considered equal to the empty string.
2. The context here is when the user presses the back button.
This will destroy all user input. But an auto-value is not user
input. It will appear again when the user realizes they made a
mistake. Nothing is lost.
Personally, I would not use the word "empty" to describe this
concept. Things like "containsUserProvidedValue",
"isCustomValue", "isMeaningfulValue", … come to mind. These are
all still a big vague. A "user provided" value can be identical
to the default or auto-value. "Custom" how? I went for
"containsValuableData" for now.

This is a direct follow-up to I6ebd020.
Steps to reproduce the bug:
* Make sure you have a template with a deprecated parameter.
The position doesn't matter.
* Add the template. The deprecated parameter is hidden.
* Add an undocumented parameter, e.g. "b". This is added to the
end, as it should.
* Add an undocumented parameter "a". This should appear before
"b", but doesn't. The reason is because the invisible
deprecated parameter is in the list that is used to calculate
the index, shifting it by 1 (or more when there are more
hidden parameters).
This patch includes a few closely related changes:
* We can loop the list of checkboxes directly instead of
indirectly via the list of parameter names.
* I made it so that an active filter only resets if it would
hide the new parameter. The original problem we had to solve
was that the new parameter would always be visible, even if
it doesn't match the filter. This awkward mismatch is still
guaranteed to not happen.

I came up with a new event to do this. This event is triggered
individually for each parameter. An alternative is a single
event that gets a list of visible parameters. Is this better?
What do you think?

This is – for now – intentionally done in a way that can be
undone. This will still be helpful for debugging for a while.
But we need to get rid of the duplication to be able to make
this new functionality visible on the beta cluster.
Actual removal will hapen the moment we actually remove the
old toolbar. There are already tickets for this.

This affects only the new sidebar. Deprecated parameters don't
get a checkbox, except they are used already. "Used" includes
parameters that are present, but empty.

This method already exists in the ve.dm.MWTransclusionPartModel
