Slideshow now supports an `-M' command-line argument to pick a monitor.

The `racket/gui' library now understands multiple monitors: the
`get-display-size' and `get-display-left-top-inset' functions accept a
`#:monitor' optional argument, and a new `get-display-count' function
reports the number of monitors.

On Unix, `get-display-size' now reports the main monitor's size by
default, instead of the virtual screen size. Multiple-monitor support
for Unix/X11 assumes Xinerama (i.e., multiple monitors on a single X11
screen, as opposed to multiple X11 screens).
