BUGFIX Fixing date/datetime handling in MSSQLDatabase

Browse Source 
Fixing the date type to actually be "date", and not "datetime" so
that values are returned as "Y-m-d" for dates, and not "Y-m-d H:i:s".

Additionally, fixing a case where using the mssql functions would
return strange datetime formats. We need the datetime field values
in Y-m-d H:i:s. To get this working, we need to inspect the field type
when retrieving rows from the database and re-format the datetime
value at this point. This is done in MSSQLQuery::nextRecord()
