Finishing a few needed things before the release: changed ShadeInput vars access from a single getAttribute function to individual methods, one for each var, for faster access (needed, since these are accessed over and over during rendering).

Very repetitive code, so I used a few macros to write it. Compiles w/o warnings here (linux, gcc 4.3.0), please report any problems.

This is just an internal change, the Python API is still the same.
