root not allowed to use crontab

[Jason Vas Dias]

There were some CVS version errors that caused this
problem - this is now fixed with vixie-cron-4.1-16 .

1. If neither /etc/cron.{allow,deny} exist, 
   ONLY root may use crontab (and now may do so!)

2. If no /etc/cron.{allow,deny} exist when the package
   is installed, the %post script will create an
   empty /etc/cron.deny file, thus allowing all users
   by default, the way the old cron used to work.
