Issue #750

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

It doesn't make sense to have a public method in Connection to
muddle around with how queries are tracked, nor for queries to
tell servers when they change (creating a dependency loop).

Instead, have the ServerEventHandler tell Server.

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.

The parser now uses the new API too, so we don't need to
do horrible things to convert.

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

With numeric formatting gone, all output is either added direct
to a window (which will be changed soon) or done through
displayable events. Message sinks are now completely unused,
as they don't affect displayable events.

Issue #426

This allows us to remove a fair chunk of the notification
handling functionality in FrameContainer.

Issue 426

I think these will eventually go away entirely, once everything
is event-bus'd, but I'm not entirely sure how that works any
more :(

We were raising notices as all coming from the local user, not
the person that sent the notice. This is... unideal.

Stop ChannelListModesRetrieved being displayable - not sure
why it ever was, we don't have a formatter for it.

Delete the duplicated methods from Connection.

Since changing to events we need to fire when changing from
unknown->away. Before, this was handled by the Server being
told about the new message (and then firing listeners).

Fixes #391.

For now this is just a straight(ish) copy of the way Server worked.
Need to make it use events in the future which should simplify it
quite a bit.

We no longer need to be consistent with the odd casing/naming
of actions.

Also remove some more parseHostname calls.

Returning null is bad.

Move to util package. Add constants for standard priorities.
