Added new StarcounterAssemblyAttribute, to be used to tag assemblies ensuring they have a resolved reference to Starcounter at compile time (for the weaver to detect them). See comments in #2216 for this.
Changed Starcounter application and library projects not to compile AssemblyInfo.cs, intended for the instantiated template.
Extended the Starcounter application- and library projects to enforce a reference to Starcounter by tagging them with the new StarcounterAssembly custom attribute.
