Sometimes I like to use facebook_form_for to show data that was previously entered on a Facebook form. It's nice to
have a wrapper for the fb:editor-custom tag that's needed to do that. The patch below adds "value_field",
which shows a field's value instead of an editable field. value_field can also be used in block form, and it wraps the
block's result with the fb:editor-custom tags, just like form_for.

I find this useful for my code, so I hope you'll accept it.

Thanks for the awesome work!
