Remove materialized views. (#908)

Browse source 
* One pass at materialized views, only about 30% faster, not good.

* Before merging master to test out bans.

* DB Rework working, still need more testing.

* Fixing accidental addadmin bug from asonix async merge.

* Fixing the comment delete trigger

* Some more DB additions.

- Adding a hot_rank desc, published desc index to post_aggregates_fast.
- Removed WITH CTE queries in favor of direct selects (since CTEs cant
  use indexes)

* Removing some unecessary indexes.

* Some more DB optimizings

- Changing the fast_id pkeys to just ids on the fast tables.
- Removing the private_message_fast, since the view contains no aggregates.
- Comment and post voting now no longer pull from the views, they update the counts directly.

* Adding community_agg_view and post_agg_views Credit: eiknat.

* Adding user and comment_view migrations. (comment_view still broken)

* Adding more views. Credit Eiknat.
