Load 'ext.visualEditor.mwsignature' (which implements VE's existing
handling for signatures), then subclass and override a bunch of things
in order to:
* Replace the context menu with a note that you don't need to type the
signature when commenting using the reply widget
* Override the sequence/command to insert signature so that it selects
it afterwards and thus displays the context menu
* Treat signatures as signature nodes when switching from wikitext,
instead of the normal pre-save transform turning them into regular
links and text

We can update the local filtered list before then, but then we would
have to do two updates for each keystroke, one to do an instant local
filter and another to back-fill the list when the remote results
become available. Currently CompletionAction is not set up for this,
and this might be confusing behaviour.

The automatic event from core didn't catch this, because it's not an action
method called "open".
