removing unused requirement

# removing unused requirement

## do we use wsgiref?

where in smugline.py is wsgiref used?

how do we avoid using wsgiref for python >= 3.2?




## smugline still works after removing  wsgiref

i cant uninstall it

	$ pip3.2 uninstall -y wsgiref
	Can't uninstall 'wsgiref'. No files were found to uninstall.

	$ pip uninstall -y wsgiref
	Can't uninstall 'wsgiref'. No files were found to uninstall.

but i can remove it manually

	rm /usr/lib/python2.7/wsgiref.egg-info; rm -rf /usr/lib/python2.7/wsgiref
	rm /usr/lib/python3.2/wsgiref.egg-info; rm -rf /usr/lib/python3.2/wsgiref

verifying that it's gone

	pip freeze
	pip3.2 freeze

and smugline still works after that

	$ pylint --errors-only --additional-builtins=raw_input smugline.py; echo $?
	No config file found, using default configuration
	0

	python3 smugline.py upload åäö --from=/c/file/txt/program/smugline/test --api-key='' --email='' --password=''

## wsgiref doesn't work with python3

>part of the build fails

it's wsgiref-0.1.2.zip's fault according to the travis output

	Downloading wsgiref-0.1.2.zip

	File "/home/travis/virtualenv/python3.3/build/wsgiref/setup.py", line 5, in <module>

	File "./ez_setup/__init__.py", line 170

	print "Setuptools version",version,"or greater has been installed."

searching for the code https://www.google.com/search?q=wsgiref+print+%22Setuptools+version%22%2Cversion%2C%22or+greater+has+been+installed.%22 return the whole file http://sourcecodebrowser.com/python-wsgiref/0.1.2/ez__setup_2____init_____8py_source.html that contain a python3 incompatible print

according to https://pypi.python.org/pypi/wsgiref it's for python < 3.2
