PHP classes and test are somewhat copies from the Popups codebase.
Some refactoring was applied. More could be done. Not to sure if
this should happen more in follow ups though.
Could also reduce the complexity of checks on the JS side. Most of
these things can only change on page load. The only dynamic part
left is the anon user setting managed by the Popups extension.
Note, that I needed to add a new PHP config for here although the
other still exists and is needed in the Popups extension. This
will change, when the user settings code also moves.
I guess it's okay for now though. Both settings default to true
and are not overridden in the config repos.
Also needed to add the Gadget extension as phan dependency.

The namespace change avoids a conflict with the existing Parsoid
implementation in Wikimedia\Parsoid\Ext\Cite and matches the current
Cite codebase better. We also need to add some phan stubs to allow
Cite to use Parsoid's generic DOM implementation classes, and some
type assertions to satisfy phan.
