Code Issues Activity Actions

WindowServer+LibGUI: Notify GUI clients about menu item enter/leave

Browse source 
We now send out MenuItemEntered and MenuItemLeft messages to the client
when the user hovers/unhovers menu items.

On the client side, these become GUI::ActionEvent, with one of two
types: ActionEnter or ActionLeave. They are sent to the Application.

This will allow GUI applications to react to these events.
