Allow affiliations to carry project ownership information; transform profile

images correctly

Summary:
This is sort of doing two things at once:

  - Add an "isOwner" flag to Project Affiliation to lay the groundwork for T237.
  - Rename the "QuickCreate" workflow to "Create" and funnel all creation
through it.
  - Reorganize the image transformation stuff and use it to correctly
crop/resize uploaded images.

Test Plan:
Created and edited projects and affailiations. Uploaded project, user, and
profile photos. Verified existing thumbnailing in Maniphest still works
properly.
