Remove tensor.__getslice__ to avoid sys.maxsize

When calling t[1:], for instance, the arguments passed to __getslice__ are (1, sys.maxsize), which is a pain to deal with, and can even not be an int (but a long). If __getslice__ does not exist, __getitem__ is called instead, with argument slice(1, None, None), which is much more desirable. __getslice__ is deprecated in python 2.6 anyway.
