Make game dll names and compiler defines for mods configurable

so mod authors can tell cmake to call it mymod.dll instead of base.dll
or d3xp.dll

and the compiler defines are also easily configurable now

I also added a comment to EndLevel.cpp, which was released with the GPL
source (and in d3xp/ it already existed in the SDK), but has not been
used to build the dlls.
