support for multiple return values from rna functions & support for returning arrays, (no functions are using this yet).

patch from Elia Sarti, (vekoon) with some modifications mainly for the python api.

- multiple values are returned as a typle in the order that are defined.
- added support for registered types returning multiple arguments (untested).
- renamed func->ret --> func->c_ret, since this only defines what the C function returns.
