Orphaning drgeo, drgeo-doc

[Jonathan Dieter]

I'm orphaning drgeo and drgeo-doc.  I originally picked them up because 
I thought our school would use drgeo, but we haven't, so I'm letting it go.

drgeo did FTBFS in the latest rebuild, and will probably need some TLC 
to get it building again.  If you decide to take this, please note that 
upstream has moved to a squeak VM image, and I haven't been able to find 
the source for it, so we're still on drgeo 1.x.
