Load the irc and common projects.

Swaparoo parser dependencies with their real projects.

Excluding 'com.dmdirc:util' nuked the project as well. That wasn't
good. Instead, just call remove on the DependencySet. That seems
to work and is a lot simpler.

This changes any com.dmdirc.* dependency references into
local project references.

It doesn't yet work for the parser as that's a different
group, and doesn't have independent projects.
