[dwm] saner ordering of clients in hg tip

Hi there,

I implemented a saner client ordering policy in hg tip. In
dwm-1.1 and earlier the order of clients in a view is quite
unpredictable when more tags are viewed at a time.

This should be fixed now through reordering the global
list of clients when performing the view() or toggleview()
functions.

Thus, any testing of this new algorithm is highly welcome.

Regards,
