Summary:
~~Two~~ Four small improvements in the sidebar, that give a cleaner look:
1. expanding the plugin section is now a small button instead of text
2. Star / unstar buttons are only shown on hover of a plugin
3. Used all caps for application names, since we are F A C E B O O K now :-P.
4. Fixed styling of loading status of apps, so that it is consistent with a fully loaded app
