- removed some unused functions from m_fixed.h. 

- removed the Build license note from r_bsp.cpp.

This note was for code in R_AddLine which had been both refactored into several subfunctions and completely replaced with a floating point version. What is left is just some basic common math without any traits that resemble anything in Build.
