Subject: [PATCH] rebuild_zebra.pl - add -y option

rebuild_zebra.pl will now mark all zebraqueue entries
of the affected record type(s) done when run in
normal mode to index all records (as opposed to running
it with -z to just process the zebraqueue).  This prevents
any running zebraqueue_daemon processes from attempting
to reindex the same records, redundantly.

The new -y swtich overrides this new behavior; in other words, if
running rebuild_zebra.pl without -z, you can specify
-y to *not* mark zebraqueue done.
