For logging to work:
1. $wgWMEStatsdBaseUri needs to point to a valid statsv endpoint,
e.g. 'https://en.wikipedia.org/beacon/statsv'.
2. $wgPopupsStatsvSamplingRate needs to be set. Note that the codebase
already contains the EventLogging functionality, which is configured
separately. Separately configuring different logging mechanisms
allows us to avoid sampling mistakes that may arise while choosing
one or the other. For example, let's say we want to use EventLogging for
10% of users and statsv for 5%. We'd sample all users into two
buckets: 50/50. And then we'd have to set the sampling rates as
20% and 10% respectively, only because of the bucketing above. To avoid
this kind of complications, separate sampling rates are used for each
logging mechanism. This, of course, may result in situations where a
session is logged via both EventLogging and statsv.
3. The WikimediaEvents extension needs to be installed. The extension
adds the `ext.wikimediaEvents` module to the output page. The
logging functionality is delegated to this module.
Notable changes:
* The FETCH_START and FETCH_END actions are converted to a timed action.
* The experiments stub used in tests has been extracted to the stubs
file.

Bug: T157111
Change-Id: If3f1a06f1f623e8e625b6c30a48b7f5aa9de24db
During the review of I71a8a848, it was noted that there was no
documentation/ADR about the use of factories over classes.
Change-Id: I29ab44b3f9c680c81fbddebc7844bd05e26f18df
This way, src contains sources, and dist contains distribution files.
Also, add some documentation about the folders in the README and an adr.

Generate changeListeners via webpack
We now use a build folder to build the JavaScript for
our ResourceLoader modules. This is the first change
in a line of changes.
A source map is provided for debug support.

The save action has been implemented, and it is listened to by the
canonical enabled state in the previews reducer, and by the settings
reducer to perform UI changes.
The enabled state of the application has been kept in the preview
reducer as the canonical source of truth. See supporting changes for
documentation about the decision.
Actions:
* Introduce new action SETTINGS_CHANGE with the enabled status
* Trigger that action when clicking Save in the settings dialog
Reducers:
* Listen to SETTINGS_CHANGE in the preview reducer to update enabled
status
* On the settings reducer
* Handle the SETTINGS_CHANGE action
* Add showHelp flag to determine if the help should be showing
Change listeners:
* Switch to compare past vs present changes in the implementation
* Handle showing and hiding the help
Supporting changes:
* On the rendered settings dialog:
* Change #hide to actually just hide and remove legacy if statement
* Add #toggleHelp method to show or hide the help dialog
* Add doc/adr/0003-keep-enabled-state-only-in-preview-reducer.md to
support the decision of making the saveSettings action creator return
a Redux.Thunk and keeping the enabled state just in the preview
reducer.
* Add NB to actions#saveSettings explaining and linking to the
document
Follow commits soon:
* Persist the settings change to local storage when it changes, and
unify with the preview change listener

Action changes:
* Include whether the user is logged in/out and information about the
current page in the BOOT action.
* Add the EVENT_LOGGED action, which represents the eventLoggined change
listener logging the queued event.
Reducer changes:
* Move all tokens and timing information from the preview reducer to the
eventLogging reducer.
* Make the eventLogging reducer reset the state.
Changes:
* Add the mw.popups.createSchema function, which constructs an instance
of the mw.eventLog.Schema object that can be used to log Popups
events.
* Add the eventLogging change listener, which logs the queued event.
* Add hand-crafted, artisanal documentation.

Supporting changes:
* Add mw.popups.registerChangeListener, which registers a change
listener that will only be called when the state in the store has
changed.
Change-Id: Ibe6934058327c7f02f7d8092e74a667a5a1c600a
Changes:
* Add an ADR for using ADRs (added by `adr init`).
* Add an ADR for containing and managing state.
