Link inspector menu not appearing in the right place

ve.ui.Widget.css
* Adjust menu up a few pixels to match other uses of ve.ui.MenuWidget (the format drop down)

ve.ui.LinkInspector.js
* Moved the form value initialization to a timeout that fires well after the animation of the inspector - this is only important because the first element has a menu that pops up and the menu was rendering in the wrong location

ve.ui.Frame.js
* Added reference to frame within this.$$ by passing it to get$$

ve.ui.Inspector.js
* Removed auto-focus on open from inspector base class - this will be done in a more specific and controlled way instead

ve.ui.js
* Added optional frame argument to get$$ so that it's easy to get the frame from any $$ that's bound to an iframe document

ve.ui.Window.js
* Removed duplicate static member assignments
* Added auto-focus on the window's frame before calling onOpen
* Added auto-blur of anything focused within the iframe after calling onClose

ve.ui.MWLinkTargetInputWidget.js
* Auto-highlight the selected item when populating a menu so that pressing enter always keeps the currently selected item selected

ve.ui.TextInputMenuWidget.js
* Take the frame's position into account when positioning a menu below an input
