#424 Add parameter support to menu editor
When adding/editing an eventhandler in the menu editor of the KalIDEoscope editor in design view, i would like to see parameter support: a popup after the popup of the name of the event handler, which asks which parameters to use for the method call.
(The text of the popup is wring by the way, it has the same text as the popup of the 'appending menu item' option)
So when adding/editing the event handler, the first popup asks "Enter the new menu item caption" (which should be "Enter the method for event handling), after entering the method name and clicking OK, there will be a new popup saying something like "Please enter the parameters for the method call".
For example, the method entered is "foo", and the parameter is "bar". The event line in the XML will look like this:
<Events>
<Event method="foo(bar)" target="menuItem1" type="MenuHandler"/>
</Events>
What this currently does: when entering the method name with a parameter, e.g. "foo(bar)" as method name, the editor opens the source of the page and creates a new method: public void foo(bar){}
