Changed the code host PrivateAssemblyStore class to return the list private binaries it knows about with a given name in the order they were registered (i.e. in the same order applications load).
Refactored assembly resolver prior to redesign; now distinguish between scoped and unscoped resolve methods.
Implemented first version of code host assembly resolver routine that resolves references not scoped (i.e. without a known requesting assembly).
Further refactoring of the assembly loader, centralizing the place we actually load a requested reference if we find a match.
Commented the code host AssemblyResolver class.
Merge branch 'issue/2112' into develop. Finalizes the redesign of the code host assembly resolver as needed to solve #2112.
