shell: handle multiple popups 

This patch implements a popup stack. When the first popup is opened
the grab is started, and it is added to a list. Further popups will
be added to this list but the grab won't change. When a popup is
closed it is removed from the list and, if it is now empty, the grab
is ended.
A click outside the client area will send the popup_done event to
all the popups in the list, and the grab will end.
