bugfix and cleanup

- BGE Shader.setSampler(name, index): index range check was wrong.
- Compositor check for an invalid channel was incorrect.
- getting the center of selected verts used an uninitalized z axis.
- do_init_render_material() used && rather then & when testing for MA_TRANSP.
- weight paint activate flipped bone used && rather then & for flag checking.
