Jump: Fixed zero-width ledge bug
While this had no affect on the player, the game would sometimes randomly generate zero-width ledges when spawning ledges, which caused a whole ton of problems with the graphic generation and CCTexture2D and was the reason that the console was spammed with so many error messages when nothing bad seemed to be happening. The game would output the errors, drop the zero-width ledge and continue on as if nothing had happened.

Fixes #217
