- updated shader programs

- fixed brightness shader
- fixing leifx shaders
- r_modelshader - enables the use of a new diffuse fragment shader for enhanced model shading
- shadespecular slightly regressed :(
- don't do libxmp for travis?
- disabled leifx gamma, seems redundant with actual gamma now
- more waterimage cruft removal. don't do this waterreflectrefract until we have fbos please
