// Original source: http://www.tutorials.de/blog/gumbos-blog-11282/funktion-zur-fehlermeldung-und-behandlung-521/
// Modificated by Daniel Marschall:
// - Allow the use of trigger_error() instead of the direct use of the error handler function.
// - Added E_USER_DEPRECATED as well as more compatibility parts
// - Respect the current 'html_errors' configuration
// - Respect '$php_errormsg' when 'track_errors' is enabled
// Problems:
// - The @ sign is not respected when trigger_error() is called :-(
