This adds support for indicating in the status line whether a given window
has been referenced more than once. In the case of grouped sessions this is
likely always going to be the case, but this also helps in showing which
windows in a session have been included via linkw, for example. Currently,
the window printable flag for this is '+'.
Also, add the corresponding #{window_references} flag for returning the
number of references on the window.
