A_07.1

Changed some println's, gave particles a variable framerate, and slowed
down the poof effect.  Nothing major.
A_07.2

+ Added jump particles (they don't activate after a certain horizontal
speed, because it looks weird having a vertical whoosh of air when
you're not moving straight up
+ Added short delay before dropping through platforms, so the player can
now superjump while on a platform
+ Added a delay timer between particle effects.  It was originally
intended to create a delay between landing and jump particle effects
because it's weird having the air move in opposite directions if you
jump immediately after landing, but I removed that functionality as it
was extremely unsatisfying not to have the jump poof for those ten
frames.
* Fixed some redundant code
