From cfecad2e0e5efc55394b282cbfbb5caa859f5d16 Mon Sep 17 00:00:00 2001

Subject: Receive eurephiaVALUES struct with config instead of char *db
 interface.

Get the database driver directly from config file.  Implemented also
log settings via config file as well, which can be overridden by
future command line arguments.
