Again some changes in the event-system:

• Added "mainstate" event-state to BaseObject. It leads to the state which was defined with the mainstate attribute in XML.
• Support event-forwarding to the mainstate of event-listeners.
• The "targets" subsection of the EventDispatcher now supports all kinds of objects (not just EventTargets).
• EventTarget now works in all places of the XML-file, not just in the "targets" section of EventDispatcher.

Added a sample XML-file which explains several aspects of the event-system.
