ResourceManager load and unload resource functions include an Archive.

[Kenix3]

• Archive will need a Map compatible comparison operator. They are the same if the Archive path matches.
• Add a new struct for resource cache lookup: shared ptr to Archive, String cache key, and String resource name. The struct will need a Map compatible comparison operator. Will string match the two string and string match the Archive names.
• ResourceManager function that take in a cache key and a resource path should take in the struct as well.
• ResourceManager functions have a new alternate version of functions that just take in the name like we had before.
