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.
