[balsa] More efforts to get HTML parts to fill the pane

[Peter Bloomfield <peterb src gnome org>]

commit 509a298991ebc1c5153a0398fd785323c7a51e6d
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Sun Oct 13 14:33:55 2019 -0400

    More efforts to get HTML parts to fill the pane
    
    * libbalsa/html.c (lbh_web_view_new): connect to "load-changed" signal;
      (lbh_load_changed_cb): call-back for it; if the load has finished,
      call gtk_widget_queue_resize();
    * src/balsa-message.c (add_part): pack the widget with expand=FALSE,
      so that an HTML part's v-expand takes precedence.
