* src/client/composer/composer-widget.vala
(ComposerWidget::action_entries): Add an entry for the inspector so it
can be loaded via the context model in the same way as other items.
(ComposerWidget::context_menu_*): Keep track of a number of the context
menu's sections, so we can selectively include them in the WK context
menu.
(ComposerWidget::on_context_menu): Re-implement to work wth the WK2
context menu model, which annoyingly doesn't even extend any of the
GtkMenu infrastrcuture.
* src/client/util/util-gtk.vala (menu_foreach): Pass the action
target through to the loop's delegate, it's a bit more useful for
dealing with the WK2 model.
(add_g_menu_to_gtk_menu): Removed, WebKitContextMenu doesn't extend
Gtk.Menu any longer so this is is no longer needed.
* ui/composer-menus.ui: Reoganise to use standard composer action
prefix. Duplicate rich and plain text clipboard sections so they can
just be selectively enabled. Include dummy sections for WK items to
specify where they are located in the menu, and a section for the
inspector.
