EDDS v1.8 update

EDDS v1.8 Changes

* Non-combat ways to clear a known dungeon, defeating the villain.

  E.g. you can hire engineer to divert a river flooding these goblin caves,

  ending the raids. Or you can poison dungeon's water supply,

  which makes all monsters there spawn Poisoned.

* Working as a dreammist pusher for Zhentarim. Dreammist itself allows rerolling

  flaw or virtue (picked randomly), but gives HOBO token.

* ASKING difficulty option, which expresses the YES/MAYBE/NO oracle system from

  the The Solo Adventurer's Toolbox through EDDS rules.

* D20 Weather, affecting daily travel, visibility and long rest.

* D20 Welcome roll upon entering a city or an outdoor adventure.

  These events like festivals, curfew and ambushes.

* D20 Weather, affecting heroes and monsters.

* Trainer type scholar, who allows training multiple skills per month,

  by paying money and spending FAVOR.

* NPC name generator.

* Clarified rules on reporting nobles and officials to guards,

  and the the city lord can't be reported.

* Clarified and rewrote Standalone section.

* Rewrite the Vecna boss to include the stats right where they needed.

* Rules on adapting HeroQuest monsters and heroes into DAS/EDDS format.

* Clarified that critical does 2x damage, and that on natural 20 target

  avoids critical if its speed is above the attacker's speed.
