luhmann/EFCodeFirst.CreateTablesOnlyv1.0.0

Adds a IDatabaseInitializer implementation for EF Code First CTP5, as a workaround for situations where you need to update the tables, but can't recreate the database. Works with AppHabor. To use simply set the DontDropDbJustCreateTablesIfModelChanged class as IDatabaseInitializer with DbDatabase.SetInitializer.
