Subject: [PATCH 2/8] Update script to also extra face data from baserom

course.vtx is the file to be #included in course_vertices.inc.c

course.obj is, as named, an OBJ file with the vertex and face
 lists for the given course

Subject: [PATCH 6/8] Complete the texture lists for every course

Also made the master material file for all course. The paths
 in that file are relative so if it or the target png's move
 there will have to be a lot of other changes made
