removed DEBUG code and added 2010 to the copyright list

- optimised drawbar() and arrange() handling for multiple monitors, arrange only arranges the relevant monitors when applicable, same with drawbar
- need to release 5.7.1

+18:17 < Biolunar> when i change my resolution in dwm (to a smaller one) and then back to the native, the top bar is not repainted. that's since 5.7.2, in 5.6 it worked fine
+18:19 < Biolunar> is it just happening to me or a (known) bug?
+18:24 < Biolunar> and in addition, mplayers fullscreen is limited to the small resolution after i changed it back to the native
+

+Donald Allen reported this:
+
+starting emacs from dmenu in archlinux results in missing configure of emacs, but mod1-space or mod1-shift-space fix this problem. this problem is new and did not happen in 1.6 xorg servers
+
+Starting emacs from xterm doesnt show this problem, he uses tag 8 for emacs

+
+This is a known bug (for some curiosity I received the same report via 
+privmail from 2 other people within one week, really strange). 
+The quick fix is commenting out the code in lines 817/818 in hg tip 
+dwm. I cannot confirm this has no side effects (I think it does) and I 
+will address this issue shortly with a real fix.

+Patching SDL, bugging them?

+
+voltaic reports this:
+
+When I use two monitors, one larger in resolution than the other, the
+bar is drawn using the smaller x-dimension on both screens. I think
+what's happening is that there are two bars drawn, but the short bar
+is always on top of the long bar such that I can't see the information
+under the short bar. If I switch to the small screen, hide the short
+bar, and then switch to the large screen, the long bar is drawn
+correctly.
+
+A similar problem occurs when I have started dwm on a small resolution
+monitor (laptop screen) and then I switch to a large external display.
+When I do this, the bar itself is drawn for the original smaller
+resolution, but the information to be printed on the bar is
+right-aligned for a longer bar. So what I see is a bar that has the
+right hand side of it cut-off. See attached screenshot.
+
+I am using standard options for xrandr such as --output VGA1 --auto, etc.
