Minor editor preference tweak
	* Made the hover controls enabled by default
	* New admin hook system and dashboard, (still in beta).
	* Switched all widgets to use the "installable" flag instead of baseurl for that attribute.
	  This just helps with confusion between those two different elements.
	* Fixed support for the "class" names on form elements
	* Zip files that have a mimetype of application/octet-stream are now detected appropriately.
	* Fixed the <aside><aside> error.  Widgets should have been divs instead of their aside.
