Log Message:
NULL column handling fixes for problems reported by Christopher Jenkins.
dco2 will keep datatypes on Nulls for rebinds, instead of snaping to SQLT_STR.
DCOracle2 scans columns on executemany() to determine to reprepare the statement
and get the a non-None value for making a type determination.
