epriestley 9196a6bd9f Use Edges to store dependencies between tasks in Maniphest
Summary:
  - Use edges to store "X depends on Y" information in Maniphest.
  - Show both "Depends On" and "Dependent Tasks".
  - Migrate all the old edges.

Test Plan:
  - Added some relationships, migrated, verified they were preserved.
  - Added some new valid relationships, verified tasks got updated with sensible transactions and sent reasonable emails.
  - Tried to add a cycle, got an ugly but effective error.
