vis-open: allow to show files vertically

It might be more comfortable to navigate through the files arranged vertically. Add ability to specify VIS_OPEN_LINES environment variable which is passed to vis-menu as -l option. It would be better to add vis option for this to set it via lua config, but it might be added later. Signed-off-by: Vadym Kochan <[email protected]>
