New OBJ exporter is missing "Path Mode" setting for exporting .mtl files. The options that used to be available were: Auto, Absolute, Relative, Match, Strip Path, Copy. All of them are important. The new behavior (without any UI option to control it) curiously does not match any of the previous setting. New behavior is like "Relative, but to the source blender file, and not the destination export file". Most of the previous logic was only present in Python based code (bpy_extras.io_utils.path_reference and friends). The bulk of this commit is porting that to C++.
