A couple more bugfixes for Lumina:
1) Try to use the window name/class to find an icon file before using the generic icon.
2) Return the system tray usage to the hard-coded 0. Apparently the numbers do not correspond to screens, but instead are order of importance (lower is better).This is in contrast to the documentation.
3) Add the special multimedia volume up/down keybindings to lumina-config
