#19 Logging and reporting of problems

[Neil Strickland]

If any of the following things happen, then AIM should
record it in a special log file, and possibly also send an
email alert to the administrator.

* Any initialization procedure or marking procedure
generates an untrapped error.

* Anyone tries to log on as the administrator, but
gives the wrong password.

* Any student enters an answer containing words
listed in `aim/SafeParse/HackNames`.
