Most changes were just replacing usage of "has_key" with "in". Also updated the sorting function which was simplified and changed to a "key" function instead of "cmp" (which is no longer supported in python3. Verified everything builds with python 2.7 and 3. https://bugzilla.gnome.org/show_bug.cgi?id=678066
