IE js bug for dropDownMenu

[tomarenz]

The js code rendered for dropDownMenu items contains a bug concerning identification of events on IE.
Actually rendered code is:

(event || window.event)

but IE (both 6 and 7) sometimes define the object event, which actually is not an event at all. The final result is a missing submit after clicking on menu items.
Safe code should be:

((event && event.button) ? event : window.event)

This solution works for both IE and FF.

And btw, code to be modified is in org.ajax4jsf.framework.util.command.CommandScriptBuilder, line #47.
Similar patches are needed in MenuItemRenderer and MenuItemRendererBase, for which it would be much cleaner to import JSR_EVENT from CommandScriptBuilder instead of hardcoding.

Well, actually it should be:

((event && event.button != undefined) ? event : window.event)
