Subject: [PATCH] Supporting xfce4-panel in dwm

We basically treat the panel as special window which
- never has borders
- always has y=0
- is never shown as active window in the indicators
- is shown on all tags

Which window? "xfce4-panel" - hardcoded by window name in dwm.c.
=> Should work for other panels as well, if you adapt.
