WindowServer+Taskbar: Let WindowServer manage the "window menus".

Browse Source 
Taskbar now simply asks the WindowServer to popup a window menu when right
clicking on a taskbar button.

This patch also implements the "close" menu item, and furthermore makes the
window menu show up when you left-click a window's titlebar icon. :^)
