Title: Replace shut down Google calculator

Since iGoogle has been shutdown, the iGoogle Calculator no longer works. Instead I pulled in the mathjs library to evaluate arbitrary math expressions locally.

Conversions aren't working as expected, removed it from the expressions to listen to. Should be doable though. At this point Hubot doesn't crash when you calculate.
