[dwm] snap-to-screen-border

Hi there,

I implemented a snap-to-screen-border feature for mouse-based
movements of clients in floating mode (or floating clients) in
hg tip of upcoming dwm-2.0. I'd like that you test this feature
before I create a new release... it's actually only 8 additional
lines of code, but I want to make fully sure it works correct.

Regards,
