Init accepts multicastif, minissdpdsocket, discoverdelay

+ Created initialize for the UPnP class.  Initializer accepts named
  arguments to override defaults.
+ multicastif & minissdpdsocket ars strduped and thus freed in the dealloc
  (tho could/should they be native py objects instead?)
+ The pymoduletest.py test has been modified to support these but I only
  tested multicastif & discoverdelay.
