New struct `View'. Replace `uri_to_control' in `EShellViewPrivate' with

* e-shell-view.c: New struct `View'.  Replace `uri_to_control' in
`EShellViewPrivate' with `uri_to_view'.
(view_new): New.
(hash_forall_destroy_view): New, replacing
`hash_forall_destroy_control'.
(destroy): Updated to match the uri_to_control -> uri_to_view
changes.
(socket_destroy_cb): Likewise.
(get_view_for_uri): Renamed from `get_control_for_uri'.  Return a
View instead of a GtkWidget.
(show_existing_view): Updated to use `get_view_from_uri', get a
@view instead of a @control.
(e_shell_view_display_uri): Updated to use `uri_to_view' instead
of `uri_to_control'.
(e_shell_view_remove_control_for_uri): Likewise.
