Summary:
Fixes T6856. Fixes T10164.
- Make the profile image composer code use the underlying icon name instead of the top-level icon key, so it works instead of 404'ing.
- Change the button to show a preview of the profile icon instead of the text "Use Icon and Color".
- When creating a new non-milestone project, automatically set the profile image to the icon + color image.
Test Plan:
- Created several new projects, saw appropriate default icons.
- Edited projects, saw icon previews.
- Clicked icon buttons to set icons.
- Poked around other applications which use builtins (Pholio, user profiles) to look for anything I broke, but everything seemed fine.
