vis-lua: support themes in vis:message

The commit that added vis:message[0] used the existing vis_message_show
function which is used internaly to display lua stack traces.  That
function uses the internal error_file.  vis_event_emit does not trigger
events for internal files in order to avoid extra lua errors when already
printing a lua stack trace[1].  Due to this setup any usage of vis:message
showed the text in a window with default theme/syntax/status bar colors.

Instead of using the internal vis_message_show function, create a new
window and file that are not marked internal in the same manner as
cmd_help so themes are applied.

[0]: 73f1fc7 (vis-lua: implement vis:message(msg))
[1]: 4811a65 (vis: properly redraw status bar of windows displaying internal files)
