Final tests for course.

These are the final set of tests I was able to produce for the course.
There are likely other good tests to be had, but we've run out of
time.  Alas.  More tests will appear in the production version of the
code.
Compile fix
Merge branch 'master' of https://github.com/geisler/game_contest_server into gmaster
Merge branch 'gmaster' into dev. 508 tests. 34.
