This will allow us to import FunOrb caches without worrying about the
risk of collisions with the main set of RuneScape caches.

I'm still not particularly happy with this: if the JS5 download
finishes before HTTP, it'll time out and kill the whole process.
Similarly, because it takes so long to import the indexes and as we
can't fetch groups in parallel with that, it can often time out early
during the process.
In the long term, I think I am going to try and move most of the logic
outside of the Netty threads and communicate between threads with queues
or channels. This would also allow us to run multiple JS5 clients in
parallel.
The code also needs some tidying up, particularly constants in the
Js5ChannelHandler constructors.

This makes us behave like a standard client that only keeps a single
copy of each group in its cache. This ensures we can at least detect
(crc32, version) collisions for a particular group, rather than silently
skipping colliding cached groups.
A disadvantage is that more bandwidth usage is required, especially if
the download is interrupted.
