TESTS: removed pp from installation test and reordered others
FF: BitsPlusPlus and BitsSharp are now working in bits++ mode as before

The mono++ and color++ shaders are NOT working as previously thought
however. It seems the shader code that I used is only good for select
graphics cards and I need to spend some time fixing that to work more
generally.
