Rename PhabricatorUserStatus to PhabricatorCalendarEvent

Summary: Ref T4375. We never join this table, so this is a pretty straight find/replace.

Test Plan: Browsed around Calendar, verified that nothing seemed broken. Saw my red dot in other apps.

Use a modern query object to query Calendar events

Summary: Ref T4375. Calendar uses oldschool `loadOneWhere()` calls. Make CalendarEvent policy-aware, do the edit/delete policy checks through the policy framework, and use modern query infrastructure.

Test Plan:
  - Viewed calendar;
  - created, edited, deleted event;
  - viewed calendar tab in Conpherence.

Rename "status" to "event" in most URIs / classes / etc

Summary: Ref T4375. This doesn't get everything (I figure I'll clean up the actual UI strings when I touch the UIs) but should get the bulk of the URIs and class names and stuff.

Test Plan: Clicked every calendar-related link I could find/grep, they all still seem to work. URIs now say "event".

Fix accidental forward dependency in old commit summary migration

Summary: See IRC. This migration inadvertently depends on the columns in the commit table, because it calls `save()`, and thus broke for installs with data after we added the `importStatus` column. Since that was ~9 months after this patch, probably not many installs are affected.

Test Plan: Ran patch locally with `--apply` on data. Had user verify fix.

Herald - add support for task priority

Summary: adds a new FIELD and a new VALUE to support this. Slightly dodgy because priorities do not have phids so we have to special case how we handle this in a few spots. Ref T4294.

Test Plan: made a new rule to get cc'd on unbreak now and wishlist tasks. verified got cc'd correctly and not cc'd correctly.
