Add PlayerProfile API to replace GameProfile
This simply provides the base API to create the objects. Further commits will come that adds
adds usage of this API to existing GameProfile based API's, as well as new API's.

Subject: [PATCH] Improve Structures Checking
Improves performance by keying every chunk thats part of a structure to a hashmap
instead of only the first one.
This allows us to avoid iterating the entire structures value set to see
if a block position is inside of a structure.
This should have pretty decent performance improvement to any standard world
that has been around for a whilewith lots of structures due to ineffeciencies
in how MC stores structures (even unloaded chunks has structured data loaded)
