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.

Log entries should always go to the file corresponding
to the Query, rather than to the user that happened
to send the message.

Closes #430

Java 8 introduces a sane API for dates; to store datettimes
we should now be using LocalDateTime.

These will be going away shortly.

This slightly changes how the logging plugin history window
works - instead of parsing dates and using DMDirc timestamps,
it just shows the logged timestamp like the backbuffer does.

As history tends to span several days this seems more useful.

Issue DMDirc/DMDirc#426

DMDirc/DMDirc#426

Start to move FrameContainers behind an iface so they can be
pulled out.

For now, just cast back when needed.
