Additional fix for the clock error (not sure if it is needed) + small update in options.

- Fixed a crash related to "clock" / "forest_network" that could happen on clients joining dedicated servers
- Added configuration option for more beaver biomes

- Added metal and chezzy biomes. The default option is "Less".
- Increased number of bunneefalos (Need to set "Bunny biomes" to "More" to have them appear)
- Updated description of "Keep original Ocean" in TE to tell that it is not recommended

Fixed names for "WaterGeneration" and "MegarandomCompatibilityWater" that seemed to be inverted (probably a Volcano bug)
Added new biome "Lava Arena" from Volcano
