Log Message:
Honour PKG_SYSCONFDIR: the package was actually looking for files in
/usr/pkg/etc so I've changed this to sysconfdir; I'm not adding an extra
search path.

Also install default configuration files in place, so that this works out
of the box.  If they are not there, the window manager is unconfigured, and
things like window menus do not appear at all.

Bump PKGREVISION to 2.
