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.

Fix the some copy and paste errors.
Add to the updater module.
Move the pattern to a field.

Keep the existing hackery until the plugins that call it are updated.

Move Updater-based providers into a separate module, and inject
the actual dependencies into the DMDircUpdateManager instead of
various 2nd degree dependencies so it can make them itself.

This should make it easier to add other strategies/download
sites/etc.
