Hook up dynafields in params.py
The helper method getDynaFields converts a list with dynafield dicts
to a dictionary with dynaproperties and is used to update the
create- and edit_dynaproperties dicts.

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.
