Issue #750

This is just an IntelliJ refactor, using EventBus in place of
DMDircMBassador whenever possible.

Stop swimming against the tide and accept what most of the rest of
the world does.

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
have to override the gradle config, and makes it nicer to work in
IDEA 2016.1.

Rework how Logger/ErrorManager interact so they can be half
mocked out (or, at least, used in a thread-safe-ish manner).

Don't ask Main for the config directory.
Remove getMain() from Main.
Everything that needs a main now either gets given it, or asks something else.
Unfortunately, a few more dependencies on the static IdentityManager.getIdentityManager()
were introduced, but they can be tackled separately.
Fix unit tests for the above.
