[Etoys] Latest Scamper fixes

[karl]

I'm not sure what the fixes to HTTPSocket were supposed to fix.
I know they broke some things.

About scamper: I noticed Scamper was in the image and that it
was not updated to the latest version. The latest version does 
not have any enhancements, but fixes to stuff already in the 
browser. 


These are the latest changes to the Network-HTML package
(From package description):
