* Prevent the realtimepreview module loading on anything
other than wikitext pages (as is already done PHP-side
but that is bypassed when loaded as a gadget).
* Give the #wpTextbox1 a class so we don't always style it.

Add two new actions for the 'preview' feature:
* preview-realtime-on – The WikiEditor 'Preview' toolbar button
was clicked to turn the preview panel on.
* preview-realtime-off – The WikiEditor 'Preview' toolbar button
was clicked to turn the preview panel off.
* preview-realtime-inuse – Fired without user interaction when the
WikiEditor preview feature is already on when the editing form is
opened.
This also adds a new hook for the last of these to use and to match
the enable/disable hooks.

Store the current state (enabled/disabled) of Realtime Preview in
