Trashed doc handling

This very simple change modifies the query builder to include posts with status "trash" in the "started by me" view, so that docs deleted by another user don't disappear into the nothing. Also adds styling for the trashed docs.

Any edit the user makes to a trashed doc (including just opening the doc and saving) restores the doc to status "publish".

Let me know if there's anything else you'd like me to do with this.
