[SAGA-RG] Python bindings naming issues

Hi folks, 'NotImplemented' [0] and 'NotImplementedError' [1] are reserved keywords in Python. Thus, the SAGA 'NotImplemented' Exception has the potential to hide some of these keywords in the Python bindings. So we could either rename the exception or live with the fact that there might be some (small?) problems. What do you think? Similarly, 'id', which is used as parameter in many methods in the SAGA spec, is a built-in function in Python. This, however, shouldn't be to much of an issue to rename.
