Separated plugins to 3 categories

There was a huge mess by mixing completely unrelated modules in 1 huge
binary, so now it's split to 3 cats: generic plugins that can be used
anywhere on IRC, WMF plugins that are useful only for wikimedia project,
and obsolete plugins that are no longer maintained, but we still want to
keep the source code, 3 dll binaries are generated, and that is just fine,
on production we will need only 2 of them (obsolete aren't used anymore)
and anyone else who want to install this bot for their own purposes surely
won't need WMF plugins
