SE_Chance_Best_in_Spell_Grp     469  Chance to cast highest scribed spell within a spell group. All base2 spells share roll chance, only 1 cast.

SE_Trigger_Best_in_Spell_Grp	470

Chance to cast highest scribed spell within a spell group. Each spell has own chance.

Additional Changes:
Rewrote TrySpellTrigger function used for SPA 340 since it incorporates SPA 469. Improved code so that chance of spell being triggered should be more accurate statistically.
