Title: First draft validation with validates_length_of

Return false/true if field values pass validations and only update when
they do.

Currently there's only validates_length_of, as this commit is more
intended to open up discussion of how to implement this in a nice(r)
way.

I need to add this myself anyways, but I would like to check with you if you have a preferred way to do this and maybe it's something I can send upstream too.
