Remade as a version-safe plugin dll, added optional public methods to control retargeting, added license and readme.

Improved handling of atypical Mass Attacks that target multiple Speed Dice of the same character. In this case, the subtarget to be retargeted into the clicked Speed Die will be chosen as the closest subtarget to the left (wrapping over to the rightmost if there are none).

Updated a common assembly to reduce log clutter.

Compatibility patch for Respectful Targeting.

Improved compatibility with other mods. Also fixed OnApplyCard being called before OnReleaseCard when reapplying the same card.
