openbor Tools

New script functions:

allocscript()
loadscript(handle, path) ...multiple times
compiilescript(handle)
executescript(handle)
...
free(handle)

Add combostyle 2 (SOR3 style).
So,
combostyle 0 = default bor pattern (default),
combostyle 1 = golden axe style (range based),
combostyle 2 = SOR3 style (chain without hitting),
combostyle 3 = 1+2 (though it is hardly needed)

Use magic number for bitmap, screen and sprite, make script resource management easier.
Remove script function getpixel, use getgfxproperty instead.
* getgfxproperty(handle, propertyname, ...)
- handle can be sprite or screen
- propertyname: width, height, srcwidth, srcheight, centerx, centery, pixel...
- for pixel, x, y must follow
- other properties such offsetx, offsety have not been added yet.

Complete palette none code.

Use palette none to disable palette and use individual palette for each frame.

Multi-byte string support for font functions.
Add a new command fontmbs in menu.txt to flag this change.

Commented out some debug messages.

Forgot to update makefile, added.

Move the sound_volume_music line behind the music line in check_music, assuming function music will overwrite the volume.

Delete long time unused sprite.c, rename spritef.c to sprite.c.
