Log Message:	I'm not usually up for putting third party sources in here, but in this case I'll make an exception. This is ukcprog, a set of useful C functions which the ihost plugins Pete's writing uses. It's got a pretty free license too. I've munged the Makefile around, as all it needs to do now is make the library, not install anything. The idea is to statically compile the other programs against this library, making the final binary independent of this code etc.
