Remove deprecated elements from selectable.py; remove lockmode

Removed autocommit and legacy "for update" / "lockmode" elements
from selectable.py / query.py.  lockmode was removed from
selectable in 693938dd6fb2f3ee3e031aed4c62355ac97f3ceb
however was not removed from the ORM.

Also removes the ignore_nonexistent_tables option on
join().
