EDDS v1.3 update

EDDS v1.3 Changes

* For the upcoming disability day, EDDS got the D6 Disability system,

  making the existing DOOM sytem more scary and scarry, when monster's

  attack rolls 20. Finally we can model a classic pirate with lost eye and

  a single leg, or, well, Vecna himself.

* Playtesting uncovered that place 4x4 tiles is cumbersome and not everyone

  has the appropriate tiles, so EDDS moves to a more streamlined approach.

  Now instead of drawing a tile, we place D20 Prop facing the direction where

  the exploring hero came. Anyone adjacent to a prop is considered to be at the

  prop's tile. That system maintain compatibility with existing DAS adventures,

  while embodying the Theater of the Mind spirit of the original RPGs.

  Room Inspection section was renamed to D20 Prop and updated accordingly.

  For start tile use either staircase or a camp tent (if outdoors).

* D12 Rural Adventure sometimes becomes part of a plains adventure.

* D20 Environment now produces large open areas, spawning all the monsters

  at once.

* When tile has several units, ranged attack into it has chance hitting an ally.

* Simplified the rule regarding attacking the monster on newly explored tile.

  It can now be attacked only if hero's speed is above the monster's.

  Speed 5+ heroes now move 2 tiles, as opposed to SCOUT heroes previously.

* Hazardous D20 Environment harming unprepared heroes, without artifacts and

  spells.

* Clarified TIRED tag, and described it under Tags Referece section.

* Casting powerful spells now requires spending FAVOR.

* Fixed several rules errors and obsolete mechanics.
