Subject: Replace usage of remaining boost::unordered containers with std
 Replace LLUUID and LLMaterialID container hashing functions with more
 collision resistant versions Utilize boost::hash_combine for TEMaterialPair
 to generate good hash distribution Generalize is_in_map and get_if_there for
 usage with all mapped types
