[feature request]: cron jobs per user via froxlor UI

[rseffner]

Describe the solution you'd like
I'ld like to give power users the ability to set up own cronjobs via froxlors web ui. In a first step e.g. just a simple editor for files located in /var/spool/cron/crontabs/ (using debian, not sure if other distros also use this path).
This feature may be dis-/enabled per user in froxlor.

Describe alternatives you've considered
I looked for ready to use crontab web ui, but found none with authentication/multiuser support.

currently already possible: allowing users to use shell access, hence allowing them to use "crontab" directly

Still a nice feature to have this in the UI though
