Provide "quick" option for loading database into RAM

Browse source 
The directory cache and the database's Load to RAM feature
each result in a much better user experience.

But, when both features are enabled at the same time, it
can take a very long time on older players - easily several
minutes for larger libraries - until all of the database's
dircache references have been updated.

Include a 'Quick' option that causes the database to ignore
dircache references which can *significantly* reduce disk
activity after booting.

\note{When Load to RAM is turned on, and the directory cache is enabled as well,
it may take an unexpectedly long amount of time for disk activity to
wind down after booting, depending on your library size and player.
This can be mitigated by choosing the \setting{Quick} option instead, which causes
the database to ignore cached file references. In that case, you may notice brief
moments of disk activity once the path for a database entry has to be retrieved.
Set to \setting{On}, if you plan to take advantage the database's Update function,
