Some updates to comments and example code.

Support for a "movement" key in sprite.ini, possible values are currently "rotating" (default) or "directional".
Replaces prior mechanism for direct directional movement, which was only good for platformers.

Sprite.moveTo(x, y)
Sprite.turnTo(bearing)
Improved Sprite.checkOverlap(margin), although it still needs work.

also try to avoid dividing by zero :|

this prevents the "big ridiculous island" that occurs when a map is processed a lot (1000's of times)

(perhaps digitalman might rename this file to terraingenerator.js)

log send errors.
remove deuce's testes.

...no really... I swear it's almost done!

(this only affects people who might be running a synchronetris server)

everything seems to be working now.

derp the derps (stable)

catch falling pieces that collide with garbage lines.
set all players to !ready after game finish.
