Correct workaround for issue #158 to allow custom portable versions.
Will need to implement it in cmake at a later time when an official portable build happens.
Removed always false check in be_ai_chat.cpp
Fixed wrong enum being used to check alphagen value.
CGEN_WAVEFORM is not the same as AGEN_WAVEFORM!
Merged ioq3 commit ioquake/ioq3@6c4d010f29cefcad1e7794674ad4a0e50d962122
