visual-mode: deselect messages after performing command

In order to better align to vim functionality: deselect visual mode
selections after performing a command on the selection. This patch also
introduces a new command to allow for re-selecting (remarking) the
previous selection set so that commands can be chained together. The
deselection only applies to msg commands that *do not* move the message
from the store (those types of commands already deselect):
- read/unread
- flag/unflag
- modify-labels
- copy
- pipe

Previous usage to mark several messages as read and deselect all:
Vjjj:read<Enter>:unmark -a<Enter>

New usage, similar to vim:
Vjjj:read<Enter>

To chain a command together:
Vjjj:read<Enter>:remark<Enter>{next command}<Enter>
