Changes since 1.155:	+78 -35 lines
Log Message:	- reworked the fxix handling more or less completely. i do see a structure now, but haven't implemented it fully. what we have will have to do. - added generic flat resource support - used this to retrieve the exp table resource - cleaned up face handling (uses less memory now) - implemented clean callbacks for face changes - halved latency for tile loading
