Removed cron cookbook since we are moving towards using opscode's.

I separated this request out for cron.  I did some research, and it appears that cron authorization is considered a bug and is currently being tracked (if I found the right place).

My opinion is that adding "users" will be very "Intuit specific" (needing vas access, needing or not needing wheel access, what home directory, etc).  Should this customization be part of a larger "Intuit user add" cookbook?  So that everything a user needs is kept together until this bug gets fixed with the opscode cookbook?

My $0.02... what say you?
