Finish "Sea Prison" area using OLC

[Synival]

The "New Thalos Sea Prison" zone should be finished for testing the OLC system. The critera for "finished" are, for the purposes of testing OLC:

1. The zone is built while BaseMUD is running in Valgrind for error-checking
2. While creating the area, the internal state of the world is monitored for correctness (within reason)
3. All OLC features have been used (minus mob programs)
4. As development continues, annoyances and potential improvements to OLC are added as issues on Github
5. The zone isn't terrible and lazy - it shouldn't be immediately deleted after BaseMUD is cloned! :P
