Title: make FormErrorHandler more easily extendable

I wanted to override FormErrorHandler so it would return error messages in the format

error:
message: Parsed error message
template: Error message template
parameters: Error message parameters

instead of

error: Parsed error message

and it's pretty hard to do with private members.
