* src/modest-tny-msg.[ch]:
        * Now modest_tny_msg_get_body tells if the original body was
          plain text or html.
* src/widgets/modest-msg-edit-window.h:
        * Now modest_msg_edit_window_new gets a new parameter
          preserve_is_rich, that sets the format to the one in the
          original message in case it's set.
* src/maemo/modest-msg-edit-window.c:
        * Preserves the plain text format in case it's requested
          (fixes NB#64170).
        * Now we reset modified status on constructor to prevent getting
          modifications from construction process.
* src/modest-ui-actions.c:
        * Use the new modest_msg_edit_window_new api. For messages
          opened from drafts, it preserves the format (plain or html).
          For other messages, it respects the configuration preference.
* src/gnome/modest-msg-edit-window.c:
        * Fill the new is_html parameter in modest_tny_msg_new method.
