Improve JavaScript event handling

By now the JavaScript event handling is pretty puristic. Mostly because of HtmlUnit but I think there are also some points were the Wetator can do better.

I have created some tests executing the currently supported actions in Wetator and asserting the correct JavaScript? events. These tests are browser dependent so I created them for FF3.6, IE6 and IE8 so far. I do not have an IE7 right now so I can not create tests for it.

The following tests are created:

• for action 'Click On' with asserts for events 'mousedown', 'mouseup', 'click' and 'focus'
• for action 'Mouse Over' with asserts for events 'mousemove' and 'mouseover'
• for action 'Select' with asserts for events 'mousedown', 'mouseup', 'click', 'change' and 'focus'
• for action 'Deselect' with asserts for events 'mousedown', 'mouseup', 'click', 'change' and 'focus'

The following tests are missing:

• for action 'Set'
• asserts for events 'mouseout', 'blur', 'select', 'keydown', 'keyup' and 'keypress'
