[plt-scheme] test case boxes in drscheme (trying to abstrat over them)

First of all, the uneditable box you're looking for now requires clicking 
the little purple triangle to see. It's the 'actual' box where the result of 
the test expression is shown.

Secondly, putting tests into a list does not currently work on purpose. 
There's actually additional code disallowing test cases to appear in 
non-definition contexts because the tool is aimed at the begining student 
languages. The test-cases also don't evaluate to a value so that there's no 
out put in the interactions window.

Implementing your feature request would require test-cases to evaluate to 
their boolean values and have output in the interactions window and remove 
restrictions of where the test-cases can go. Definitely no impossible but 
would need some consideration of the pros and cons.

Thanks for your feed back. I hope you like the tool.
