Adapted code to work with LOVE 0.8.

Previous working version was 0.3.
Other than function name changes, these are the major updates:
 * Images now use upper left for positioning rather than center
 * Constants now use string literals instead of LOVE defined variables
 * Color objects no longer exist
 * Degress changed to radians everywhere
 * Configuration file is now a lua file
 * Color mode must now be modified to affect text color and not images
 * Animation class was removed, but a backwards compatible third party one was added
 * Animations now start at frame 1 instead of 0
 * Lots of other small changes to how things work
