Branch created to handle robot.name problem

Error in lita-hello, see robot.name branch for lita-hello.

This repo will need to be updated to keep up to date with lita-hello.
Updated the bundle for new lita-hello

Updated and reinstalled the bundle to now switch over to generic robot.name's.
Also included .bundle in the .gitignore
Fixing merge conflict
Updated Gemfile to use Ruby 2.0

Bot was crashing every now and then randomly. It was on Ruby 1.9.3 when it should have been 2.0.0.

Gemfile now reflects this.
