RE: [GT] SVN Commit r589 - in trunk/GT: . DB

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

Some explanation of this commit....

Previously, DB::Text supported different formats for the market file: GT
format, US format, and EU format. The recent rewrite dropped this choice
and replaced it with the use of Date::Manip::UnixTime, with 2
consequences:

1. It is exrucitingly slow, compared to before.
2. EU format cannot be parsed.

I rewrite 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. If you
do not change your options, the Date::Manip version is used, and you
will not notice a difference (well, there is some additional error
handling in case the date format in the file is incorrect).

Further, this change reuses GT::Prices::loadtext in both DB::Text and
DB::HTTP, making them both consistent and allowing easier maintenance.
Note that DB::HTTP had not been updated to use the same options as
DB::Text, when DB::Text was changed. Now they are both consistent again.

Please let me know if you find any problems with this change.

Cheers, Th.
