Merge pull request #34 from csmith/master

Remove weird circular dependency.
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.
