Added facility to selectively ignore EnterNotify events

This will be used to avoid some situations where an EnterNotify event should not
focus the window beneath the mouse cursor.  For example, when a menu (or any
window for that matter) is unmapped, focus should not pass to whatever window is
beneath the current location of the mouse cursor, but to the previous window in
the focus list.

This was first noticed when using the ClientMenu feature with
focus-follows-mouse on -> The focus would always end up on the window beneath
the mouse pointer, not the window selected in the menu.
