- fixed endless loading world if "caves" is enabled.

- Integrated code from wingsummer: Ban ice island
- added a nil check for maxwelltakler in maxwellendgame (thanks 인민해방전쟁이다 for the bug report)

0.994:
- reduced amount of warlus camps in both worlds they do spawn. On DS and easy difficulty it now only shouldbe up to a maximum of ~16 (not including a mactusk town)

- made grass boat recipe unavailable, if only wormholes should be used to get from island to island.

moved hardcoded strings from maxwellintro to the ASVENTURE_STRINGS file (thanks wingsummer)

On world start, danger close to the start position is removed now, to prevent instant death (this does not affect enemies/fire spawned by maxwell-intro)

fixed crash on worldgeneration

fixed adventuremod crash when modsettings for first level was "worldsettings"

fixed crash on world generation, sry =/

Finally the generation of fireflies/maxwell-lights in the darkness level is working again (new code, so it may be different to DS, but I think it is near enough).
On non-DS modsetting also cave-flowers, pigtorches and rabbithouses will be generated all over the world.
