[e-lang] Idea: SturdyRef debug printing

[Kevin Reid]

Idea:

Make SturdyRefs, if their referents are NEAR, print them:

   <SturdyRef to <counter>>

instead of

   <SturdyRef>

This would be useful for debugging, and it would not reveal any 
information not already available to holders of the SturdyRef.

Edge case: if an object which has a private reference to a SturdyRef 
uses that SturdyRef in its __printOn, then the print of the referent of 
the SturdyRef will be revealed where it would not before. I don't know 
if this would be a problem.
