[balsa] Use is-maximized instead of window-state-event

[Peter Bloomfield <peterb src gnome org>]

commit 67c3c68e457fd22d329f15379021b23605fe87e5
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Thu May 25 11:09:35 2017 -0400

    Use is-maximized instead of window-state-event
    
        * src/main-window.c (bw_notify_is_maximized_cb),
        (balsa_window_new): connect to "notify::is-maximized" signal
        instead of "window-state-event" to avoid irrelevant state
        changes.
        * src/main.c (real_main): increase the fix-panes timeout again,
        from 600 to 700 msec.

        Revert 45b7ce83a56690beb40c37f911f7c61b553d8828, and just
        increase the timeout from 500 to 600 msec.
