offer plugins to claim screenspace

[jeroen]

• Player will support a method for requesting space via flashvars to the right, left, top, bottom for other use (e.g., viral.size=50 viral.align=right)
• Resize event will provide plugins with event object containing display data (w,h,fs,x,y) and a hashmap of data: pluginName -> x,y,w,h,fs

So this should be a little easier in r94:

• all scaling logic is now combined in Controller.redrawHandler()
• AFTER all plugins have been loaded, the Player fires a redraw event, which fires the redrawHandler().
