python3 support

[jtrip]

When I try to use this with Python 3.4 I am receiving an unexpected error.

Traceback (most recent call last):
 File "/usr/local/bin/journal", line 9, in <module>
   load_entry_point('journal==0.4.0', 'console_scripts', 'journal')()
 File "/usr/lib/python3/dist-packages/pkg_resources.py", line 356, in load_entry_point
   return get_distribution(dist).load_entry_point(group, name)

   return ep.load()

   ['__name__'])

   print "journal: error: config file '" + args.config_file + "' not found"
                                       ^
SyntaxError: Missing parentheses in call to 'print'

I am tempted to see if I can fix it myself, just thought I would post here and see if you or anyone else had taken a look at Python 3 support. Maybe it is just fixing some print statements (easy) or maybe there will be more to it.

Fix away! I haven't touched this project in awhile, but it was written for Python 2.7. I'd support upgrading it to Py3.

My understanding is that targeting Py3.5 as the default and using 3to2 to backport makes sense, but I've also seen six used to support py2/3 at the same time.

I just submitted a pull request for python3 compatibility. It's my first ever pull request, so any feedback is appreciated!

I will take a look
