ufo:ai - license problems and packaging

[Florian Ludwig <dino@phidev.org>]

Hi again,

thank you Teemu for the patches / changes / additions. 

  * Rename ufoai-data-music to ufoai-music, install just ogg-files
    instead of packing into pk3

I guess its because of putting .ogg files in a zip-archive is not
"useful" in terms of compression you've done this? 

  * Set BASEDIR to empty string
Why?

Florian
