Xworld - Another World interpreter for Rockbox

Co-conspirators: Franklin Wei, Benjamin Brown

--------------------------------------------------------------------
This work is based on:
- Fabien Sanglard's "Fabother World" based on
- Piotr Padkowski's newRaw interpreter which was based on
- Gregory Montoir's reverse engineering of
- Eric Chahi's assembly code

--------------------------------------------------------------------
Progress:

* The plugin runs pretty nicely (with sound!) on most color targets
* Keymaps for color LCD targets are complete
* The manual entry is finished
* Grayscale/monochrome support is NOT PLANNED
  - the game looks horrible in grayscale! :p

--------------------------------------------------------------------
Notes:

* The original game strings were built-in to the executable, and
  were copyrighted and could not be used.
* This port ships with an alternate set of strings by default, but
  can load the "official" strings from a file at runtime.

--------------------------------------------------------------------
To be done (in descending order of importance):

* vertical stride compatibility                          <30% done>
* optimization                                           <10% done>
