Stylefixes in access.py and removal of self.deny calls
The result of self.deny() is not very helpfull to the user, as such
we should not use it if we can provide a more sensible message.
Also made the document access checks use getForKeyFieldsOr404 to
prevent an error page when the specified document doesn't exist.

"""
The md5 and sha modules are deprecated since Python 2.5, replaced by the
hashlib module containing both hash algorithms. Here, we provide a common
interface to the md5 and sha constructors, preferring the hashlib module when
available.
