OO-1493: update to TinyMCE 4.1.9, do the remove of the editors in the DOM replacement routine in function.js ( this prevents leaks of editors in some case )

OO-848: enhance the interface of course nodes to do a post copy processing different from the import one

OO-1472: extended EnrollmentNode configuration. changed EnrollmentManager, RunController and BusinessGroupTableModel to handle the new configurationState

no-jira: bugfix, changed from replaceAll() to replace() because there is no need for a regular expression which leads to a redscreen when a bad groupname is given
