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…
