[Owncloud] CronJob System within ownCloud

[Frank Karlitschek]

One of the design goal os ownCloud is that is should enable as many people as possible to host an ownCloud instance. So someone with jut a webspace at a university for example should be able to run ownCloud by just copying ownCloud into the webspace.
A solution like this System Daemon wouldn´t run in this scenario and would require significant more knowledge to install and run than currently.
