Audio: Add AudioManager and Main Menu music
nothing, just fix in nullgamelogic
Nothing (just a little fix)
AudioManager: Play some sounds!
Audio: Switch ogg files to WAV

It seems like jME's OGGLoader has a bug which makes it
freeze on short sounds! I'm tired of stupid Java libs
so I'll just work around that by using WAV files directly
for short sounds, and ogg only on lengthy sounds.

Audio: Add more sounds, reencode OGG sounds

Turns out the VLC Ogg encoder does crap and makes the EOF
crazy. Adobe Audition warns that the file is corrupted at
the end, and it seems like jME's Ogg decoder just go crazy
(ie. freeze/infinite loop) when it encounters such thing.
Re-encoding ogg sounds through Adobe Audition seems to
fix the issue.
