These effectively duplicate the master index tables, but in a less
flexible manner - as they don't support importing a master index where
some of the indexes are missing.
This commit also combines MasterIndexImporter with CacheImporter, to
make it easier to re-use code.

I have a small collection of these from when I ran a service that polled
the JS5 server for the master index back in 2009. We'll probably be able
to find some in old Rune-Server threads too.
They'll be useful for verifying caches with an unclear provenance.
