Before this revision, trying to read a Date field using xmlrpc would
result in a marshalling error.
This is due to the fact that 960360afe4
changed the internal value of Date/Datetime fields to hold
datetime.date/datetime objects.
The xmlrpc layer is capable of converting datetimes to the XML
datetime representation, but this is not possible for datetime.date
objects.
In order to solve this, the Marshaller class used by python's
xmlrpc.client is overridden and monkey-patched, allowing to convert
datetime.date / datetime.datetime objects into properly formatted
strings.
