openbor Tools

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.

Re-adjust enemy attack chance after playing some mods. When there are too many enemies on screen, their chance to attack is also lowered. Because the new ai patterns tend to swamp on the player, difficulty increases too much when there are more than 5 enemies.

Reduce the chance for the default grab. Previous logic will prevent the entity with a greater index from grabbing another with a smaller index when they are both walking.

Check transparent bg for 8bit water (though it is rare).
Fix enemy stuck bug when multiple items overlap each other and some of them are not pickable, also reduce their chance to chase items.

Optimize 8 bit water.

Move sprite_map and sprite_list declaration from types.h to openbor.c
