Title: Quick Restart Unicorn regardless of Gemfile Changes. 

Unicorn will now always do a zero-downtime deployment even if the Gemfile has changed.

In `unicorn.conf.erb` the possibility of a changed Gemfile is already handled, so it is safe to do a quick restart.

The `clean_restart` function is left in place for anyone who needs it for a different context.
