Objectives:
* Rename this.$ to this.$element
* Rename this.$$ to this.$
* Get rid of the need to use this.frame.$$
* Rename OO.ui.Element.get$$ to OO.ui.Element.getJQuery
Changes: (using Sublime Text regex patterns)
* Replace "get$$" with "getJQuery"
* Replace "\.(\$)([^\$a-zA-Z])" with ".$element$2"
* Replace "\.(\$\$)" with ".$"
* Replace "'$$'" with "'$'"
* Set this.$ to null in constructor of OO.ui.Window
* Set this.$ to this.frame.$ in initialize method of OO.ui.Window
* Replace "\.(frame.\$)([^\$a-zA-Z])" with ".\$$2"
Bonus:
* Use this.$() in a bunch of places where $() was erroneously used

* Button title
* New experimental files
ve.*.MWAlienExtensionNode.js
* Very basic extension of ve.*.MWExtensionNode
ve.ui.MWAlienExtensionInspector.js
* Default to inline-block for wrapper. Should probably
get rid of styled wrappers for GeneratedContent eventually.
ve.ui.MWAlienExtensionInspector.js
* Basic extension of MWExtensionInspector. Override title to
use tag name e.g. '<easytimeline>'. Could be changed in future
to 'Extension: easytimeline' or similar.
