Small resque recipe improvement

Hey guys,

I've updated the resque recipes that I found in your example-cookbooks repository. Resque failed to start at my Scalarium managed EC2 instance, and it was a real pain in the back to figure out why it didn't start. I discovered that the resquectl script didn't redirect the STDERR pipe correctly, and thus no error msgs where visible in the resque logs.

Once I redirected the output properly, my Rails environment started complaining about missing a HOME environment variable. It turns out monit doesn't set this properly. So I prefixed the launchctl command with correct environment variables in the monit config.

This also might be helpful for other people trying to run Resque on Scalarium. Let me know if you need any further information on these small patches.

Cheers,
Stefan
