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.

Define a 'plugin' function to use in place of 'project' that
will figure out where the plugin is living in the root gradle
project.

This allows the plugins to be included and built properly
when they are in a submodule of either the client or the meta
project.
