[Etoys] DrGeoII for OLPC

Having the DrGeo code in the image is indeed an option. But, we  
cannot do this for each and every Squeak-based activity - there are  
too many interesting additions to include them all, and people will  
surely continue to create new ones. So installing some additional  
package for Etoys should be simple - and both Hilaire's SAR and  
Stef's PR downloads work fine for a one-time use, but do not work yet  
with the Journal. I was hoping that someone would come up with a way  
to make this work, and also hopefully a really efficient one.
