Made proto's Netbeans Friendly

Dunno what you did but I just ranted off a bit and accidentally deleted
it so tl;dr

WORK IN THE NETBEANS FOLDER AS A NETBEANS PROJECT
THAT MEANS INCLUDE YOUR SPRITES
PLANE GAME CANNOT RUN WITHOUT THE SPRITES
Sidescroller works fine
Don't open the file immediately with a comment, at least put it after
<!doctype html> to be safe it doesn't break again (if that caused the
file corruption)

Note: Ask Thar about embedding files, at the moment our game would be
better in Flash or Java due to multiple files.
