Added DivisionOperatorFix option for signed integer division (#278)

Browse Source 
* it changes the behavior of vanilla division operator to use signed
integer division. Before it used signed division for floats but
unsigned for integers.

Added a new "div" operator for unsigned integer division.
Moved mathematical script functions from Utils.cpp to new Math.cpp.
Added include guard to sfall.h and main.h in modders pack.
