Updates GLES1 support for CoglMaterial
This updates cogl/gles in line with the integration of CoglMaterial throughout Cogl that has been done for cogl/gl. Note: This is still buggy, but at least it builds again and test-actors works. Some GLES2 specific changes were made, but these haven't been tested yet.
