Added different sprite type options to editor. Need to flesh out health
in UI to really take advantage of it.
Health is working: Bees decrease bonzos health not as fast as original
game; this can always be tweaked later. Need to implement now fall
damage.
Added fall damage; still needs tweaking.
Removed spurious DamageEffect class in src folder

Tweaked more variables to get better fall damage calculations. Now uses
exponential increase of damage based on fall.

Fixed all sounds in default.zip to load properly, although underlying
issue still exists with sounds less than 6K.
