ALF-10771: DiffContext is now passed around to provide the DB Dialect.

Browse Source 
Instead of the Differences being passed around on their own, the DiffContext is able to provide more information -- at present just the Dialect. The dialect can be used to change the way database objects are validated or differenced.
