Mostly whitespace changes. No bug fixes. Q3Rally doesn't change any botlib code so revert copyright in botlib headers that use to be in the Q3 SDK game source directory. MD3_MAX_* defines (besides MD3_MAX_LOD) are not used so revert to ioq3 values.
Update to ioquake3 revision 3306 from 1951 of the ioq3 Github repo via subversion. Over 4 years of changes.
