To have a more visible cursor on unfocused windows this patch makes st draw a
rectangle around the terminal cell.

Thanks Mark Hills <mark@xwax.org> for the suggestion!

The copying and pasting in the terminald and GUI world is flawed. Due to the
discussion on the mailinglist it seems that sending '\n' is what GUIs expect
and '\r' what terminal applications want. St now implements that behaviour.

Thanks to stargrave@stargrave.org for the suggestion!

People sending me patches against strange revisions and basing on their own
revisions make me having to reapply them. Then such errors appear.

The specified font[] pattern need not have a medium weight. It could be
specified as a number too or have a different weight other than medium.
