Partially fix Bug#16403.

* rect.el (rectangle-mark-mode): When the region is not active,
display a message saying that the mark as been set and that
rectangle mode is in use.
(rectangle--highlight-for-redisplay): Only put an overlay with a
visible vertical bar when (display-graphic-p) is non-nil.
This partially fixes Bug#16403.
