Added DynaFields to the dynaform module
DynaFields work similar to DynaForms, in that they allow a regular
field to be created by supplying a dictionary.
The main advantage is that any property can be added, even if the
base class doesn't have support for it.

"""
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.
