This is an initial, rudimentary attempt at integrating the scheduler
into the kent hierarchy. There are likely gonna be drastic changes
in the future, and i haven't even tried running the whole thing.
But hey, the code compiles again now!
Ardix is being relicensed to GPL v3 or later. I have no idea whether you
can just do this if you feel like it or if it has any consequences, but
i kinda don't really care that much about it. Any changes made after
this commit will definitely fall under the GPL though, and considering
that only few things are really working yet anyways this is good enough
for me.
