EDDS v1.4 update

EDDS v1.4 Changes

* Sentient items and props (see Special NPC).

  Since many campaigns and settings require these. E.g. LoTR's Ring of Power.

  Such items propagate their virtues, talents and flaws onto owner.

* Legendary Items are now randomly generated to make use of the sentient

  NPC items, support other features and improve uniqueness of each adventure.

  Such items are purely mechnical with narrative left to players and DM.

* Before talking to an NPC, you can decide what tone to use.

  That influences the applicable skills. See Skill Related Actions / Talk.

* Rescaled gp into the 50:1 to make counting easier.

  I.e. 50gp are now 1gp, so we can use d20 to count gold amount.

  Values below 50gp were treated as TRIFLE anyway.

* Secret passage to the dungeon goal, uncovered by interrogating monsters,

  or inspecting suspicious rooms.
