tagcache: add a setting for customizing the database path

Add a new setting,

    database path: /path/to/folder

to change where the database files are stored, which allows it to
be shared by multiple builds when using multiboot. This avoids the
need to maintain a separate copy of the database for each build.
This setting can only be set from the config file; it has no menu
option yet (due to lack of a GUI to pick the directory).
