OpenBox moments

I was annoyed by the strange behavior of gnome, so I decided to switch back to a lightweight window manager.
Now it's Openbox moment.
Configuration was easy, following the Arch Wiki.
Added some effect with cairo-compmgr, pypanel for taskbar/systray, conky and some clicking on obconf.
The result is a good looking gui; I leaved also xdm, /sbin/login works fine (updated the .zshrc post, see for details) and last but not least regenerated menus with mmaker -vf OpenBox3.
