Updated to allow for multiple 'applications' to add users to cron.allow and cron.deny via a defined type (cron::allow_deny_fragment).

Hej @ljkimmel,
thanks for your contribution ! I am working on this in my repository here:
https://github.com/Phil-Friderici/puppet-module-cron/tree/allow_deny_fragment

I'll do some minor refactoring and add spec tests for the new cron::allow_deny_fragment define.
Once finished, I'll come back to you and ask you to verify my changes.

Thanks & phile grüße
