Subject: [PATCH] - The abort() routine from the Output module is now also able
 to display a link   at the bottom of the error message. It is a direct
 wrapper to the error()   routine.   Thus, the following error messages now
 contain a link at the bottom:   - File not found   - Accessing above the
 virtual root directory   - Creating an object above the virtual root
 directory   - Directory where Dev-Editor should create an object does not
 exist - It was possible to access the directory containing the virtual root
 directory.   Well, it was only read-access.
