Until now, type related cronjobs where bound to find their data at the default location. As soon as you set another webroot by supplying the custom_webroot parameter, the jobs did not found their executable and did not run anymore.
With this fix, all type related cronjobs will lookup the corresponding webroot set by the type or manually. Also, we changed the group those cronjob files belong to, to enable you to look at the global cronjobs by using the devop user for debugging purposes.
Closes #44
