- Fix loading of non-existent resources (not elegant and not checked everywhere yet, the resource system is subject to a minor rewrite anyway)
- Rename more Klayman stuff
Sounds and music play now in some scenes
(I didn't change the comments to code in all modules yet)
- Fix calcHash to ignore non-alphanumeric characters, this fixes at least
one animation glitch (when inserting tapes into the player)
- Move SoundResource to sound.cpp
