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.
