Restartless about:me

I plan to use about:me in an other extension that is built on top of [jGlome](https://github.com/glome/jGlome). In order to provide a bit better UX I have patched your code to make about:me boostrapped. The added bootstrap.js was inspired by [Edward Lee's example](https://github.com/Mardak/restartless/blob/examples/registerService/bootstrap.js). 

Please feel free to check (and pull) these changes. 

Many thanks for this nice add-on!
