Libcod for windows

[Mitch]

I added basic support for 1.0. But i haven't tested all the functions. So it might be that some functions don't work yet. Probably the entity and vector return value.

I also included kung's injector loop (with a dll check).

Edit: status 1.0

Working
- All param functions are working (string, int, float, vector)
- string, int and float return functions are working
- ip/ping are working

Not working/untested
- Vector, entity and array return functions haven't been tested yet
- All player functions haven't been tested yet (except ip/ping)
