Deleted Items folder

As suggested here: ​http://forums.zotero.org/discussion/308/deleted-items-collection/

Rather than the implementing as a collection, as suggested, it might make the most sense to just add a new DB table and add some NOT IN's to queries.

New method Item.trash() to insert itemID into the table?

Escalating this item to blocker. Should be implemented prior to public beta.

Adds handling for parent/child items in trash -- non-deleted context items will appear in gray, and "Restore to Library" and the delete keystrokes won't be available if any of those are selected

Like other search views, Select All will select only the deleted items
