Summary: Adds notification icons for Conpherence and re-writes the CSS a bit for the new icons and states. I removed the background bubble here and went straight CSS. I also seem to have a JS error and the notification menu doesn't display, but I'm tired and wanted to look at this in Differential. Will update after JS fix.
Test Plan: Turned on notification numbers and conpherence numbers, turned them off. Made them big. Checked FF and IE.
