csd: add support for a visible border 
When we’re using CSDs, we’ve up until now rendered a 5px invisible
border. This border handles interactive resizing. I.e. hovering it
changes the mouse cursor, and mouse button events are used to start an
interactive resize.

This patch makes it possible to color part of (or the entire) border,
with a configurable color.

To facilitate this, two new options have been added:

* csd.border-width
* csd.border-color

border-width defaults to 0, resulting in the look we’re used to.

border-color defaults to the title bar color. If the title bar color
hasn’t been set, it defaults to the default foreground color (just
like the title bar color does).

This means that, setting border-width but not border-color, results in
a border that blends with the title bar.
