Stop swimming against the tide and accept what most of the rest of

While it adds an annoying depth to the actual source code, it makes
the root directory nicer (no more 'test-res' dirs), means we don't

ConfigFile can manually do it - it's not that much more work.
Everything in DMDirc has been moved to use Guava's Multimap.

Apply a bunch of style fixes.
