Make save dialog ready for async initialization

initialize() is currently called synchronously, but once the CSS
transplantation code is fixed and it goes back to being async, that'll
cause problems.

* Add this.setupDeferred and use it to defer setupCheckboxes() until
  after initialization
* Move code populating the edit summary from ViewPageTarget into
  MWSaveDialog and use .setValue() rather than manipulating the
  TextInputWidget's DOM. Defer this until after init as well
* Move clearing of the diff from ViewPageTarget into MWSaveDialog,
  and don't connect it to the transact event at startup, only when
  we've actually shown a diff
* Remove swapPanel( 'save' ) from ViewPageTarget, instead do this
  on setup in the dialog itself

Bonus:
* Document events
* Get rid of onFooButtonClick handlers in favor of array syntax
