[plt-scheme] Error-in-file

It is possible -- if you were to create an instance of a snip% class
that responds to clicking and then use `write-special' on the
error-port, that snip will show up in the drscheme window. DrScheme
does this for the bug icon (plt/collects/drscheme/private/debug.ss is a
good starting point).

This is a security hole, however (since the user's program can do the
same thing, and the callbacks will then be executed on DrScheme's
thread/custodian/etc). We have been thinking about how to plug it, but
haven't yet. Still, be warned that we do hope to plug it sometime.
