Weird v-change-cron-job behavior + collaborative CLI documentation updates

Thanks @eris

CHANGED TO:
v-change-cron-job admin 8 '20' '00' '*' '*' '*' '*' 'sudo /usr/local/hestia/bin/v-update-user-stats > /dev/null 2>&1'

RESULT: hestia cron job command changed to: “hst_install_backups”

FYI: Double quotes based of your previous solution here: V-change-cron-job

Any thoughts?
