[arch-dev-public] Dropping goocanvas1

To keep up the initiative of dropping old stuff, I will be dropping goocanvas1, the only real user still using it is shutter. Felix mentioned that it can be dropped since it already depends on a lot of old libraries. I will drop pygoocanvas tonight and later this week shutter, perl-goo-canvas and goocanvas1 will hopefully disappear. -- Jelle van der Waa
