Add Unit Testing support

[gpoppino]

Just add at least one unit test to the bot for a start.

What could be tested? A good candidate is the NewsReader class and its methods:

• Adding a feed
• Removing a feed
• Listing feeds (that should be consistent with the adds and removes)

Also consider subscribing to Travis CI for Continuous Integration support.
