bugfix: do not assume ':number.screen' as the result of 'DisplayString()'

Browse source 
a newer xlib recently changed the result of 'DisplayString()' a little bit:
instead of returning ':0.0' or ':1.0' it yields ':0' or ':1'. our code to
transform this string into something that includes the currently used
Screen worked only on something like ':0.0'.

we now find the '.' after the ':' and strip that part away.
