I have made it so that it is possible to access extra card fields through the script as many, many templates are suffering for no good 
reason as a result of them not being scriptable. I understand that the gamme shouldn't be allowed to rely on them, but the styles 
should, and as such, they should definitely be accessible from scripting.
