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.

<?php
Remove three ancient columns from Maniphest tasks: attached, projectPHIDs, ccPHIDs Summary: Before edges, we stored some of this stuff directly on tasks. - `attached` was migrated to edges in Jan 2013. - `projectPHIDs` was never used, as far as I can tell? - `ccPHIDs` was migrated away and dropped more than a year ago. None of these columns are used in modern code (instead, modern code uses edges). Test Plan: `grep`, browsed around, `bin/storage upgrade`, unit tests.

// From 2013-2016, this migration moved dependent tasks to edges.
