Restructure to standard maven/gradle layout.

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.

Change dependencies after parser group change.

DMDirc/Parser#23

Ignore flakey test.

This fails reliably for me locally, but seems to pass CI. There's
some non-detminism somewhere, I guess.

Update dagger and raven.

Update dependencies

Use Connection not Server in ServerManager.

Fix counting of events.

Events aren't unread and shouldn't affect the display colour of
a window if they're hidden.

Add formatting action highlights.

Closes #669.

Specify background colour for highlight events.

Allow colours in formats to be hex. Closes #631.

Fix ordering of highlighted messages. #669.

Change highlights into proper displayable events.

Instead of wrapping the source event and modifying it, they are
now proper events that are displayed themselves (and the original
message is suppressed).

This allows highlights to be formatted differently.

Issue #669

Fix NPE in ShowTopic...

Closes #682

Only rejoin channels that active when disconnected

If a channel is parted for any reason other than a disconnect
(e.g. a local /part, or a remote part/kick) then the channel
shouldn't be rejoined on reconnection.

Closes #667

Track reasons for parting in Channel.

We'll use this to decide whether to auto-rejoin or not.

Issue #677

Add a checker for nightly updates.

Delete duplicate resources.

These are all present in res/, so there's no need for them
to be in src/. I think we just forgot to delete them after
switching to proper resource dirs.

Add a couple of tests for UpdateManagerImpl.

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

Simplify how we determine network names.

Guava provides a nice class which uses the public suffix list,
so we can ditch all of our hand-crafted logic and pathetically
small list of top level domains and do it properly.

Use KeyStoreLocator in CertificateManager.

Closes #664

Add a KeyStoreLocator.

This provides a nice interface to find a system-wide keystore
for us to use for trusted certificates.

Issue #664

Remove child event busses.

Closes #662.

Fix HighlightManagerTest.

Add source checks for eventbus handlers.
