Feature Request .restart command

[scott-wyatt]

It would be nice to use the REPL to restart an app.

Proposal

• .restart - should restart the web server.

@tjwebb currently .stop() under the repl crash like this :

To do the .restart maybe something like you do with trailpack-autoreload will fit perfectly.
