- Implemented Bank Constructor object.
- Merged Pyramid object into common Bank class. Banks can now grant
spells as part of their reward.
- Move bank config code to config/objects/creatureBanks.json. Note: WoG
banks are not updated yet, should be moved to WoG mod.
- Updated AI code so it can correctly evaluate bank danger (should be
generic enough for use with other objects)
- New files JsonRandom.* that contain routines for loading random
objects from Json (still WiP but should be stable)
