Added color output support

[wilt00]

These changes are much more a matter of taste than my other fixes, so I'm giving them their own branch and pull request.

This pull request implements simple (and kind of poorly optimized) colorization for news output. A more robust solution would probably be to use termcolor (https://pypi.python.org/pypi/termcolor) but this was simple enough to do.
