Merge pull request #3 from d3mcfadden/master

New features + cleanup
Adding jspeak/echo and history tracking for last 10 chat items

The history will allow the bot to ref things in the history.

Right now can ref the last thing in history using bash !! syntax.

Example:
jbird > hello world
d3mcfadden > jgoogle !!
AuntJackie > google.com?q=hello+world
