Rename to jumpup hipchat + other goodies

## :warning: WIP :warning: 

This is almost done and it should also be enough to close GH-1, GH-2 and GH-3. We just need to add some docs about integrating it with projects and do a clean up on the README.

I'm heading home now, so if someone wants to continue the work on it today feel free to do so :-)
