Fix for Freestyle built-in style module sketchy_multiple_parameterization.py not working correctly.
Suitable for inclusion in 2.67a.

Logical AND, OR and XOR operations on freestyle.Nature instances gave an error in some cases.
The updated C implementation of these bitwise operations is intended to reproduce the following Python implementation:

class Nature(int):
def __and__(self, other):
return Nature(int(self) & int(other))
def __or__(self, other):
return Nature(int(self) | int(other))
def __xor__(self, other):
return Nature(int(self) ^ int(other))

The problem report was by plasmasolutions on IRC, thanks a lot!
