* Evolution-Composer.idl, evolution-composer.c
(impl_Composer_show): "Forward as iCalendar" uses set_body, so we
can't make the composer un-showable after doing that. So get rid
of the "cannot show" exception.
* e-msg-composer.c (e_msg_composer_set_body): Prepare the composer
to be shown in its weird state: Put an explanatory message in the
body, then call disable_editor.
(disable_editor): Common editor-disabling code - makes the editor
and attachment bar insensitive and disables any menu items that
could be used to modify them.
(e_msg_composer_new_redirect): Use disable_editor here now.
