Add PATCH to WSGIApplication.allowed_methods

I also tested this approach and seems to work, would be awesome to have it include in the next release

Yes. Pretty please :)

Please add this for all the BackboneJS developers!

Until the patch gets applied, the easiest workaround is to subclass webapp.WSGIApplication.

class WSGIApplication(webapp.WSGIApplication):
    allowed_methods = frozenset(('GET', 'POST', 'HEAD', 'OPTIONS', 'PUT',
                                 'DELETE', 'TRACE', 'PATCH'))

Or monkey patch an instance

Thank you gentlemen! That works for me...

PATCH, please.
