Post jam fixes

There were a couple minor things bothering me that I fixed as I cleaned up some jam code into my framework:

• Artifacts along the edges of clouds. Love2d has issues drawing sprites at non integer positions from spritesheets without padding, but I didn’t get around to loading the spritesheet with padding. (I loaded the player with padding, but needed to generalize that code to different sprite sizes.)
• The toy box threefonts image font had one font with a missing character so I couldn’t use it for lowercase text. There was a fixed version posted late in the jam, but I didn’t get around to using it until now. The stylized look of the other font grew on me, so I kept it in a few locations.
