* rename `current-run-status' -> `set-run-status'
* coverage should work fine with non-textual submissions
* added `current-error-message-tweaker', "checker.ss"-based checkers now use it
to show which expression caused an error ("handin-server.ss" uses
`tweak-error-message'). (This feature is a hack, and currently undocumented)
svn: r5415
- uses a plain prefix-style log
- does not save the log to log.ss (customization options will be coming up)
* Use that in the status servlet too
* Renamed `LOG' to `log-line'
(it is now just printing to the current error port)
* Reformatted doc.txt, and some code
* Always use Content-Disposition, with `inline' for non-wxme files
* Moved run-status to private
svn: r4831
