/****** Bedienungsanleitung ******


Da der CSS-Ordner im Chrome-Ordner erstellt wurde, CSS-Dateien dort ablegen - speichern.
Diejenigen, deren Dateiname mit "xul-" beginnen, diejenigen, die mit ".as.css" enden, sind AGENT_SHEET,
andere außer USER_SHEET werden gelesen. Da der Inhalt der Datei nicht überprüft wird,
darauf achten, @ Namespace Angabe 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


Verwenden des in "view_source.editor.path" angegebenen Editors
Ordner kann geändert werden, indem ein Pfad in "UserCSSLoader.FOLDER" eingefügt wird
