We have three main ways of running rake commands in 1.2:

• bundle exec rake on source or Debian installs
• scl enable ruby193 'rake ..' or ruby193-rake on EL6 or SCL installs
• rake on Fedora installs

Personally I've found it hard to write docs for these as every time a rake command is mentioned, I have to explain which variant to use on which OS. If we didn't, people would copy and paste and it wouldn't work.

Solution: add a foreman-rake command, much like ruby193-rake, but that runs the correct thing. We can change what command it runs via the packaging in exactly the same way as foreman.spec modifies dbmigrate today.
