[plt-scheme] awkwardness in automarking

You want to script MrEd to run your students' programs in the  
appropriate teaching language. Everything else is unfair and a bit  
lackadaisical on your TAs' side.

P.S. load is NOT available in Advanced. Ask your TA's what language  
they used. If they say "R5RS" ask them to read the design document  
for HtDP and why ANY "industrial-strength" PL is inappropriate for  
Beginners.
