/****** Bedienungsanleitung ******
CSS-Ordner im Chrome-Ordner erstellen, CSS-Dateien dort ablegen - speichern.
Diejenigen, deren Dateiname mit "xul-" beginnen, diejenigen, die mit ".as.css" enden, sind AGENT_SHEET, 
alle anderen außer USER_SHEET werden gelesen. Da der Inhalt der Datei nicht überprüft wird,
darauf achten, die Angabe von @namespace nicht zu vergessen!
CSS-Menü wird zur Menüleiste hinzugefügt
Linksklick auf Stil, zum aktivieren/deaktivieren
Mittelklick auf Stil zum aktivieren/deaktivieren, ohne Menü zu schließen
Rechtsklick auf Stil zum Öffnen im Editor
Strg+Linksklick zum Anzegen im Dateimanager
Verwenden des in "view_source.editor.path" angegebenen Editors
Dateiordner kann in Konfiguration geändert werden
