* message-list.c (on_row_selection_idle): new function, actually
calls select_msg.
(on_row_selection_cmd): register an idle instead of calling
select_msg directly. this fixes the lag before the row is
selected - selection is instantaneous now, with message loading
happening afterward.
* message-list.h: add row_to_select and an idle_id to the message
list to make the select_msg call happen in an idle func.
