EDDS v0.4 update

EDDS v0.4 changes

• Hero Generation
• Hunting/Marauding for a RATION.
• Danger level for each hex.
• MONTH now consists of 20 days to simplify the rules. E.g. pick/count days
with d20, determining night time.

like Vecna and Tarrasque rampaging the countryside.

• Basic Zhentarim quests.
• Rule improvements to spells like True Polymorph.
• Minor clarifications and grammar fixes.
