Project revamp part 2: Edit

Summary:
Taking a pass at revamping the edit pages in Projects. Specifically:

 - Remove EditMainController
 - Move actions from EditMain to Profile
 - Move properties from EditMain to Profile
 - Move timeline from EditMain to Profile
 - Move Open Tasks from Profile to sidenavicon
 - Add custom icons and colors to timeline

Feel free to bang on this a bit and give feedback, feels generally correct to me.

Test Plan: Edit everything I could on various projects. Check links, timelines, actions.
