Easily create child nodes without specifying URIs

[seebi]

this is a clone of AKSW/OntoWiki#37

I'm trying to use OntoWiki as address book with the vCard schema[1]. In this schema, addresses are not string properties on the vcard/person but properties of child nodes that are linked with the http://www.w3.org/2006/vcard/ns#adr property.

Adding such an address child node in ontowiki is not easy, because when clicking "add property" you may choose the address type, but have to provide an URI. I'd rather have that URI autogenerated by selecting the type of the child node.

Short: When adding a property, I'd like to be able to specify the type of the resource instead of its URI. The URI should be autogenerated then depending on the type.
