This place is much better in so far that it much more obviously gives
us the guarantee that the sidebar and the content pane are always in
sync.

According to my test one of the two places where this property was
used is impossible to reach with the property set to false. This is
the one I remove in this patch.
This also removes a related method that is entirely unused.

Leaves a reference in the TemplateDialog so that we can slowly
migrate the many usages.
Makes no other changes to how the sidebar is managed (yet!).

The only event in use is "set". The others are never used. Which makes
sense. The driver for everything related to adding or removing parts
is the model. This widget is at the receiving end.

Bring over the ES and Less implementation from ooui-js and rename to
fit it into the VE hierarchy, but don't make any other substantial
changes.
Inlines the wikimediaui-themed styles, ignoring apex styles, and
hardcodes the Less constants.
