Improve Profile API to directly extend Yggdrasil, Resolves #1117
This improves plugins like Citizens that rely on direct instance of Yggdrasil implementations.

Instead of wrapping, directly extend and override the methods.

Went ahead and wrapped all of the services in prep in the base patch, then features modify what they need
