Completing Force/Recall Holds

Completing Force/Recall Holds

Add support for the Force and Recall hold types to be something other than
just aliases of Copy holds.

Both holds are made to cut in line over *all* other holds and both ignore
all hold rules, including copy, location, and status holdable flags.

Recall holds, when they reach their destination, will be flagged to be sent
to cataloging.

In addition, to place either kind of hold you need a new permission at the
copy's circulation library:

COPY_HOLD_FORCE for force holds
COPY_HOLD_RECALL for recall holds

Also, some re-ordering of logic should result in a fix for issues with
capturing holds as transits and/or suppressing holds and the hold shelf
logic.
