Fixed crash that happend if a player leaves and rejoins during maxwell talking. (Thanks Kova)

Fixed bug:
Host was not able to talk to maxwell in the checkmate level.
(you can examine him to "chat" with him)

Improved the code to choose worlds:
- Made sure every world is only loaded once per runthrough and every chapter gets his world (like it is intended)

This will only affect newly started adventures.
You can see in your logfile the chosen worlds for your current adventure, search for:
Adventure Mod: The Following worlds will load:
It may be, that due to the old bad code, one or more worlds will load more than once, although it is unlikely.

- Fixed crash on Checkmate (final level) if one player is a ghost or dies during cutscene.

- Fixed possible problem if GEM API mod is active, undoing some worldsettings. (thanks Zarklord)

Made fireproofness of backpack and blueprint in King of Winter level last longer (50 instead of 20 seconds), so your chances are better to get them before they burn while maxwell is talking.
(if setting is on DS, I do not add any fireproofness, like in DS. In setting hard, there wont be any items at all)

fixed crash when completing the teleportato, sry for that =/

- teleportao in checkmate level will teleport you to maxwell, just like in DS
- Health, Sanity and Hunger are now transfered to the next world (will overwrite the teleportao-mod setting)
- added customization options for world size, seasons and daycycles for each world. Default will be of course the already preconfigured values.
- made the testcode now final, so no network for the maxwellintro (so only one player should see his personal maxwell) and the "no repick" setting will now work and force you to load the same character in next world.

- fixed crash for checkmate world on difficulty hard.
- ~halfed the amount of spiderdens in darkness level (from ~300 to ~150) to reduce lag. Should be still enough spiders.

- improved the code for wormhols not spawning to near to ocean.

Now I'm done with updates :D
At least if you dont report bug, I hope there are none =/

disabled test loading checkmate....
(I hate updates :D)
