wmaker: set the window manager's information

Browse Source 
According to EWMH specification, the active window manager is supposed
to set some information. Those can be gathered for example with
'wmctrl -m'.

Before the patch:
$ wmctrl -m
Name: N/A
Class: N/A
PID: N/A
Window manager's "showing the desktop" mode: OFF

After the patch:
$ wmctrl -m
Name: Window Maker 0.96.0
Class: wmaker
PID: 6866
Window manager's "showing the desktop" mode: OFF
