SqlDateTime overflow exception persisting default values

[pcoombe]

This would apply to both v3 and v5 branches

Column type for localdate gets generated as date
Column type for localdatetime gets generated as datetime2

Parameter type for localdate gets generated as datetime
Parameter type for localdatetime gets generated as datetime

Default values for localdate and localdatetime is 1/1/0001 can therefor not be persisted due to SqlDateTime overflow exception

PR raised #12 to apply correct types to parameter
