Construct PlayerProfiles in the database manager

- New method, DatabaseManager.loadPlayerProfile(String playerName)
 - PlayerProfile no longer has magic numbers that were mapped from two different sets of magic numbers, they have migrated to the DatabaseManagers where they belong
 - Will now be possible to convert SQL -> flatfile, once command is added
