Negative duration values #41

First of all thanks for this module. I am using it for my soap library (https://github.com/mvantellingen/python-zeep/).

A user reported an issue (https://github.com/mvantellingen/python-zeep/issues/486) that an error occurs with one of the requests he is doing. It turns out that the response is a negative duration value (PT-60S). A quick google turned up some modules (java) which do indeed allow the creation of negative durations. Not sure if it is in the standard or not.

There is precedent for supporting this format; see MomentJS: moment/moment#2955. Our mixed Java-Python team would benefit from this as well.
