v0.3.0

Added

• make art makes PSP and Vita icons and backgrounds from the pictures in
  your own game data (aitd --stage=pictures dumps them). The Vita
  packages get an icon, a LiveArea background and a start-up image, and
  the PSP builds one EBOOT per game with its own title, icon and
  background.
• aitd --stage=pictures writes every full screen picture of a game's
  ITD_RESS.PAK as a PPM file.

Changed

• make dist packs the PSP build as one folder per game, ready to copy
  to PSP/GAME/.
