Crontab issue.

The kaltura install adds multiple entries to the crontab and doesn't check to see if there are already entries in it for itself (a.k.a. matching the same commands + path). Our server (after installing kalturaCE multiple times) became overloaded and crashed due to over 30 entries for kaltura services.

Solution:
In the install script check for entries in the cron that are duplicates of whatever is going to be created.
