FOR THE LOVE OF GOD, DO NOT CALL ME IF YOU CANNOT FIGURE OUT HOW TO
INSTALL THE PROGRAM.  SEARCH THE WEB ON PSP HOMEBREW.  READ THE

JUST CALL UP CHRIS AND ASK HIM. NO. NO. NO.

    SQUARE+LTRIGGER: show the text from the imported pgn game
		     return to game from pgn text view
		     
    SQUARE+RTRIGGER: removed (was toggle pondering)

pgn import - parser is not extremely robust but should work in most
cases
	
fixed compiler warnings
	
fixed small bug in random playback - if no file was found based on
original g_background_music_file no random file would be selected.

please share your piece images at:

RELEASE 0.29

new options to allow you to change the piece images.  You can turn on
external pieces and set the pieces file to the png of your choice.
refer to pieces.png for the format.  each piece is 32x32.  must be
PNG.  If anyone makes some cool pieces, please share them with me and
other users.  You can email them to chess AT bowron.us.

display option: external pieces (default off)
display option: pieces file

random mp3 playback - picks random mp3 from /PSP/MUSIC
options->music options->backgrnd music
	
RELEASE 0.28
	
castling support in wild5 and fischer random - redid all castling code

mp3 background music (slows down computer a little more than mod file)
--> switching back and forth and back between mp3 and mod is not working.
mp3->mod->mp3 and mod->mp3->mod may cause crash.  mod->mp3->mp3 is
fine. Bottom line:  if you want mp3 music, switch from mod->mp3 and do
not switch back without restarting pspChess.

selectable background music

	   write evaluation function (see evaluate_bce())

	the options menu

cleaned up evaluation code a bit - easier to understand what's going
on.  If anyone wants to write up another evalation function for a new
personality, feel free to do so and send me the code.  I would like to
have selectable opponents in the game. (if you modifiy anything
outside of evaluate() please use different function names so that I
can drop it in without name conflicts)
