Added fixes for Capistrano start/stop tasks and god-rb Email Settings 

Hello,
  I'm using your daemon-kit, it's pretty awesome actually, one of my daemons is running in production now. I've added some fixes in the Capistrano and God-Rb Email settings. 

  I've tested this and they are working well.
