Replacing god by monit, first version of config files

Still to be properly tested and adjusted in a production environment.

Update monit configs and add scripts to start services

We need scripts to wrap the initialization of delayed_job and resque so it
works properly with rbenv.
These scripts were tested in a staging server and work well except when monit
is running as a daemon, something still to be fixed.

refs #370
Fix wrapper scripts for monit and restart services with capistrano

The scripts were using the wrong method to get the path, causing errors when
running them from monit's daemon.

Added also checks to see if tmp/restart.txt was modified and restart the services
if so. This way monit will restart all services when capistrano restarts the
application.
