Enhanced battle scene; draw NPCs on map

Added text to battle scene for feedback when selecting an option from
FanSelect. Fixed broken FanSelect when there is only one option. Added
new human skin that is tinted red from the existing one for the single
NPC that is on the world scene map right now. NonplayableCharacter has
code copied from Avatar for animation and grid update purposes that will
be useful later on. Fixed Celdroids Client Desktop/run.bat.
