Title: Run `rbenv rehash` in background to speed up shell startup

I found that the rbenv plugin was slowing down shell startup time by seconds. This is because `rbenv rehash` is slow.

My commit changes `rehash` to run in the background. However I am unsure of what the origin suffix `^&1` does so this my be nieve. I leave it up to your judgement :)
