Add transaction-oriented editing to projects

Summary:
  - Make some editing operations transaction-oriented, like Maniphest. (This
seems to be a good model, particularly for extensibility.) I'll move the rest of
the editing operations to transactions in future diffs.
  - Make transaction-oriented operations publish feed stories.

Test Plan:
  - Created a new project.
  - Edited an existing project.
  - Created a new project via quick create flow from Maniphest.
  - Verified feed stories publish correctly.
