New advice during gameplay + shop items

On the right hand side of the screen, there is an advice box that will update throughout the game and give you some tips on how to play. Last update made this easier to read, and this update added some new advice, and content to the game shop. 

This is to introduce go terms to new players, hopefully lessening the burden since these advice snippets are pretty small and digestible. 

In the beginning the user gets opening advice, and then gets more middle / endgame advice as the game progresses.
