EDDS v1.9 update

EDDS v1.9.5 Changes

* Greatly simplified skill training, getting rid of the TRAINED tag.

  Now heroes with skill level N spend N XP to attempt improvement.

* Character Aspects and Monster/DC Difficulties

  A framework for player to give heroes custom abilities,

  and grounding them into the EDDS rules.

  Now you can have a d20 Spiderman vs Batman fight in Faerun,

  as long as you can declare areas of expertise (aspects) for both characters.

  If you prefer it visual.

* Bugfixes and improvements to existing rules.

  E.g. you can treat even D20 Oracle rolls as possibility of the opposite answer

  under specific circumstances, described by another D100 Prompt.
