GetCVarFixed

fixed a_GetCVarFixed(str name)

ZDoom provides GetCVar for ints and GetCVarString for strings, but doesn't provide a way to retrieve the value of float CVars. ACSUtils implements GetCVarFixed by calling GetCVarString to retrieve the value of the CVar as a string, and parsing it with ACSUtils number parsing functions.

If the CVar's value is outside the range of fixed-point numbers, the function returns 0.0.
The function is called a_GetCVarFixed and not GetCVarFixed because GDCC defines its own broken GetCVarFixed, which causes a compilation error if another function named GetCVarFixed exists.
