alfred: Add a lightweight framework for running facter scripts that feed data into alfred every 5 minutes

Alfred expects to be fed data periodically, but there's currently no easy
way to do that from scripts, prompting people to write whole C programs
to accomplish tasks that could easily be scripted.
Provide a really simple framework to run scripts every 5 minutes, using a
cronjob, when alfred is started by the init.d script.
