BGE patch: Add NAND, NOR, XOR, XNOR controllers.

NAND controller is an inverted AND controller: the output is 
     1 if any of the input is 0.
NOR  controller is an inverted OR controller: the output is 0
     if any of the input is 1.
XOR  controller is an exclusive OR: the output is 1 if and only
     if one input is 1 and all the other inputs are 0.
XNOR controller is an inverted XOR: the output is 0 if and only
     if one input is 0 and all the other inputs are 0.
The NAND, NORT and XNOR controllers are very usefull to create
complementary outputs to start and stop actuators synchronously.
MSCV project files updated.
