Added IsExtinction fix, disabled targetable slot checking until Speed Dice roll.

Fixed some inconsistent behaviour regarding targeting specific units and specific slots (this may let enemies target supposedly untargetable entities, but only when they specifically choose to and not at random).

Remade as a version-safe plugin dll; added fixes for IsOnlyAllyUnit and IsValidTarget in autoplay; added license and readme.

Improved handling of multi-target pages.

Fixed a case where an untargetable speed die could be targeted if the page was dynamically played during combat, and updated a common assembly to reduce log clutter.
