Couple little improvements to CreateAccount

UserTitle and RLGender can be set now when creating an account!

Sending MaxMaturity and MaturityRating on signup is a option now, if not defined MaxMaturity defaults to adult, and if MaturityRating is not defined, it defaults to whatever MaxMaturity was set to. 

Also cleaned up how password is sent a little bit, can use Password(should be used in new code) and PasswordHash(keeping so won't break old code) interchangeable since they both are plain text, then hashed C# side anyways
