Forgot that not all of Ground is converted to PDO yet, so am converting more of it.
Aside for some of the older classes such as Dynamic_Query which I am not sure what to do with, Ground is now fully converted to PDO.  Added testing for the core Ground PDO query functions.
Lots of work on Ground tests.
Merge branch 'master' of github.com:silentorb/ground_php
Lots of work on Ground, particularly fleshing out Ground_History.
