Check signature item type and responses in enketo validate

[malcjackson]

This is a feature request for Enketo validate, not core enketo.

When a form template is uploaded and includes an item with an oc:external value of 'signature', enketo validate should check that the item with this attribute is of type select_multiple, and that it has only one possible response. If this item type or response list requirement is not meant it should return an error.

Thanks! I actually implemented this in master, but I made it a warning instead of an error. I will change that.
