Title: Fixes getting result value for custom fields.

While implementing a form that contains a custom form field, I found out that the
result.valueForHtmlField(fieldName)
method would not return the value for custom fields.

So I propuse this small fix to the library.
Not sure if this is the correct of going about this, but it worked correctly for me.
