re-commented singleton section.
added some semicolons I forgot and removed some unnecessary logging
fixed singleton card enforcement if lines uncommented (was doing nothing)
For the previous changelog, only uncomment 278-281, not 277, my bad.
Commented out commander specific 1 quantity setter by force when removing duplicate cards. If you'd like to enable this feature, remove the "//" on each line from 277-281
