Widget Accordion Tabs
Changing Tabs to slideToggle()
widget-accordion Removing unnecessary note
Scope controlTabs to control container

Click event handlers from other controls were effecting each other.
Result was the widget could not expand if there was an even number
of widgets in the sidebar, since they would all cancel each other out.

Use toggle code as found in WordPress core's widgets.js
Add live in-widget-title

Normalize JS methods to be camelCase
Merge pull request #12 from x-team/widget-accordion
