Sequences stripping out duplicates

[JoeSimmonds]

I recently ran into a problem validating a form containing a list of items. If the user entered duplicate values in the list then the validations removed the duplicates.

I think I've tracked the problem down to the toMap call in the spm function here https://github.com/jto/validation/blob/master/validation-form/src/main/scala/Writes.scala#L42 which is removing duplicate keys from the map.

I have a solution for our project which involves our own version of the spm function.

Is my interpretation of this as a problem correct? If so I'd be happy to prepare a PR with our fix and some tests if that would help.

thanks
Joe
