The gate 34 tests were not running any tests because there was no
tox target. This changes tox-tmpl.ini (and the resulting tox.ini) to
add support for python 34 and remove support for anything that is
not py34 or py27-based.
To make the python3 tox environments work, the remote zip of a suds
fork has been replaced with suds-jurko, a relatively modern fork of
the original suds that supports python2 and 3.
Some tests needed to be fixed to deal with two main problems:
* reponse bodies being bytes
* Exceptions not having a .message attribute (.args[0] is used
instead)
* the test_flask tests were not being run for python3, they are now
* wsmeext/sphinxext.py intermittently fails due to the dictionary
changing size in flight, getting the keys prior to iteration fixes
it
Both 27 and 34 should be running 420 tests as of this commit.
