Schedule rake using cron on rvm environment

Little tricky to get this going. The key is knowing rvm environment.

$ rvm env --path
/auto/home3/delacs/.rvm/environments/ruby-2.0.0-p353@RailsDev

For rvm, basic command line tools like gem, rake and ruby are in the wrappers directory.

$ crontab -l
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
HOME=/auto/home3/delacs
RAILS_ENV=development
