cybernetic shapes

[Thorsten Roggendorf <schrotie uni-bielefeld de>]

Hi,

the cybernetic shapes are imho ready. I fixed the colors and the icons.
But I could not yet pursuade myself to get going on the Makefile.am and
.sheet (internationalization) files. Until when do I have to do it to
get the shapes into the next release ... or is dia already frozen to a
point beyond introduction of new shapes?
