Brought back an old universal clipping script and updated it to work
better - well, at all. Can now decide between wl-copy, xclip and xsel
and will do so in that order.
Can take clipping material from the following arguments (will clip any
and all following arguments) or from stdin. Stdin has precedence.
Not much more to say really, but makes writing other applications a bit
more universal when they rely on this universal little tool.
