Allow existing VACUUM options to take a Boolean argument.

Browse Source 
This makes VACUUM work more like EXPLAIN already does without changing
the meaning of any commands that already work.  It is intended to
facilitate the addition of future VACUUM options that may take
non-Boolean parameters or that default to false.
