Animations and show/hide of panels now performed in CSS

The JS now add/removes CSS classes to control the opening and closing
of debug panels and the toolbar itself
Default theme now uses CSS for animations and show/hide of panels
Updated bootstrap theme to fix CSS animations.

Fixing the active panels to "height:auto" meant they would not
animate since browsers will only animate to a fix width. I applied
a default fixed height as well as a couple of overrides for some
short panels.
