Fixes several bugs reported by members of the Discord channel.
Request Challenge Roll button now appears in Talent rolls
Extra damage 20 plus works when using both Active Effect and sheet field
Defense is now only applied once to Defense calculation
Fixed differences in buttons and sections in Talent and Spell tamplates
Contracted Special Attack to Sp. Attack to reduce cases where long talent names break formatting (names longer than 29 characters still break the formatting). A proper fix for this requires severe changes to all templates, so we have this instead.
