Rob Moen 81c9b72db5 Introduce dialogs
Major changes:

demos/ve/index.php
* Renamed ve-demo-content to ve-demo-editor

ve.init.mw.ViewPageTarget, ve.init.sa.Target
* Added handlers for dialog events

ve.ui.*Dialog.js
* Added skeleton classes for dialogs

ve.init.Target.js
* Create abstract class methods for Target.

ve.init.sa.Target.js
* Create Standalone target view methods.

ve.init.mw.Target.js
* Added MW specific target view methods.
* Integration action buttons are now added to the edit
view in the toolbar.

ve.Surface.js
* Simplified constructor, now requiring a target which contains the container

* Other changes include some documentation and code cleanup.
