RE: [GT] scan.pl error

["Weigert, Thomas" <weigert AT mst.edu>]

I am rewriting DB::Text to allow a choice between using Date::Manip,
Date::Calc, and GT format. This flexibility was possible before (well
excluding Date::Manip) the recent change, and should be restored. 

The recent rewrite of DB::Text is excruciatingly slow compared to what
was there before. For those of us who use textual data it is not
feasible to rely on the current version.

Note further that the flexibility afforded by Date::Manip is not needed
for dealing with market data.

So I will restore the options we had before, and also provide
Date::Manip::UnixDate as an alternative. This will be set in the conf
file as it was before the recent rewrite. 

It will be transparent to users that do not need the faster data
loading.
