Cron-alike admin module

[WanWizard]

With more and more functions requiring background processing, there is a need for a common way to schedule and process 'cron' jobs from different modules.

Also, not all users have root access to their webserver, and/or the ability to run PHP scripts from cron and/or the commandline.

The new module should therefore provide the means to trigger a background job from a page request, a bit like described here:  http://www.bitfolge.de/pseudocron-en.html
