[dev] [dwm] [patch] Hide window border if window is only one visible, and bar is hidden

Hi,

Attached is a patch that causes dwm to remove a window's border when the
bar is hidden, and the window is the only one visible - that is, when it
is the only client on the tag, or the tag is in monocle mode. It's
dependent on pertag, which I use, but it could easily be hacked to
remove this dependency.

Issues:

- If you move a window to another monitor, it won't get resized to fill
  the extra borderpx*2 columns and rows until you switch to that
  monitor.
- If you have more than one monitor, it'll be a lot harder to tell which
  is focussed if borders have been removed on both. You'll have to look
  for solid/hollow terminal cursors etc. This is just personal
  preference, but is worth pointing out.

I don't speak C so this patch is likely very code inefficient and ugly,
and it may well have other bugs. Do let me know if you find the time to
clean it up.
