Split the random article retriever from the rwik command function.
Merge branch 'master' of https://github.com/TCFMark/phenny.git
Created .fact command which does as issue #2 specifies. It's not very
pretty though.
Discovered that I'd left a phenny.say in the wikwrapper so removed this.

Also implemented what is probably a horrible hack to retrieve only the
nice sentence in the random Wikipedia article before mangling. This
still returns nonsense (which was the goal, I guess), but is much easier
to look at (in most cases).

Fixed #2.
