* same icon in manager
(didn't change the editor config icons as those aren't for usercss)
* "external" icon for USO styles to avoid confusion
(opening a tab is an extremely different action)
* smaller paddings in popup
* removed hover effect on label text
(necause native <select> elements cannot be expanded from js)
* various fixups
the problem we fix is that since we add the styles asynchronously, the browsers, esp. Firefox, sometimes apply transitions from the null/default state to the one specified in the injected CSS.
