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.

This is a top-level project, containing all of the submodules.
It seems to work with gradle properly.

Hasn't yet got the settings from the other project.

`./gradlew clean cloverAggregateReport` in meta will create a new
report for all the projects with tests.

Plugins that don't have any tests won't show up at all.

That didn't work :)

I've added them to .gitmodules but ignored the repos themselves.
Hopefully this means everyone can just do `git submodule update
--init --remote`, without us having to commit updates every
time one of the repos changes.
