IML file updates.

Remove serverlists.

Add away colours to IDEA project.

Ignore some more dev profile stuff.

Add installers to VCS roots.

Change project language level.

Told you so, Greboid! ;)

Change dependency rule for circle.

Switch CI to java 8

Add JSR305 to util

Add KEYS file.

Add an IDEA file

Not entirely sure what this is... Seems important!

This contains public PGP keys we'll be using to sign releases.

Instructions are cribbed from the files used by Apache projects.

Tell IDEA which nullable annotations we use.

Add way to run the client from IDEA.

The "Run DMDirc" configuration will run DMDirc with the profile
dir set to etc/profile, which is set up with a symlink to
the latest plugins.

For now, copy the defaults and mode aliases there too, as the
dev client won't extract them.

Remove weird circular dependency.

Plugins depends on the main DMDirc project for some reason.
It shouldn't. That's weird.

Tell IDEA some things aren't unused.

Add installers submodule.

Update the others to current HEAD, randomly.

Add circle.yml

Remove Gerrit stuff + update README.

Correct IDEA instructions slightly.

Propagate transitivity when switching modules.

Transitivity is *very* important when we're bundling dependencies.
Without this, the IRC plugin includes all the dependencies of the
parser (including "common"), which means it ends up with its own
version of common classes and can't be called from the rest of the
client. Not having an IRC parser is... unideal. This was very
confusing, which is why the commit message is randomly 8 lines
long. But it's over now; thank you for reading.

Add run config for remote debugging.
