Improved the GE database access to use a basic reference counter for the connection that automatically closes the connection when no one is using it anymore

Grand Exchange now uses the GE sqlite database's price index table to track price changes
Removed the old price index (confusingly called GrandExchangeDatabase.java)
Grand Exchange prices are now dynamic and influenced by trades (weighted stepping average price)
Fixed GE interfaces not loading on login
