Subject: [PATCH] Force all submitted judging words to lowercase before mapping

This fixes the bug revealed in the previous commit so that the test
suite now passes once again.

The server now doesn't apy attention to the capitalization that a
client happens to use when providing a judging submission, but will
treat things as equivalent regardless of case differences.
