Apparently the first commit (59ae429972)
did not include all files.
Furthermore the used script tended to produce funny results in certain
cases. This has been fixed and as a result thereof a few more changes
were made in this second run.
* NULL plugins have a shortname of L"Retracted" which excludes them
from being listed as a plugin in Mumble >= 1.2.4
* NULL plugins are valid plugins that always return false on trylock
so Mumble <= 1.2.3 gets behavior close to what recent Mumble has.
* NULL css, dods, tf2 and hl2dm plugins as they have been replaced by link support in the source engine.
