[dotNetRDF-develop] Use of string.GetHashCode() for database identety

[Michael F. <fr...@gm...>]

As far as I can determine from the code in eg. UriNode.cs, dotNetRDF
uses string.GetHashCode() for database identety. This is bad design
because the string hashcodes are not stable accross .Net version nor
accross architecture:
