* implemented vial of dragon blood
* problems with teams discovered:
maps with noncontinuous player occupancy (e.g. only red and teal) crash on loading. hideTiles has obvious bugs - loop goes through teams and team numbers, but fw.player is set to team number, as is the 4th argument to getTielsInRange.
* improved formula for necromancy to match better OH3
* Support for new town structures:
- Lighthouse
- Colossus
- Guardian Spirit
- Necromancy Amplifier
- Soul Prison
* Updated changelog
* Support for Lighthosues and Obelisks
* Bonus system extended on players
* Army speed won't affect movement points when sailing
* Picking grail position (digging not implemented though, puzzle map only partially)
* Minor improvements
