SilverLight: Implement event redispatching

[GoogleCodeExporter]

We should redispatch events from the plugin on the canvas element so that 
events work. We need to at least forward the following events:

click
dblclick
mousedown
mouseup
mousemove
contextmenu?
keydown/up/press?
mouseover/mouseout?

focus/blur ?

I think they be handled by a fully transparent div on top of canvas tag.

I have done a similar behavior by adding image hotspots. Works well.
