[pycrypto] documentation for PKCS1_PSS.py is incorrect, plus minor issue w/ _slowmath.py

In the file on lines 41 & 42 it has:
>>> signer = PKCS1_PSS.new(key)
>>> signature = PKCS1_PSS.sign(key)

The second line is incorrect.  It should be:
>>> signature = signer.sign(h)

Oh, there is also a bogus assertion in _slowmath.py:

On line 85, it asserts that e is long.  If you have an e of 3, it is reasonable for e to be a normal int, and not a long.  Maybe the asserts should be changed to:
n = long(n)
e = long(e)

So that python will convert the types properly.
