Update Bootstrapping with more data

Create labels, and recipies and label recipes from table dumps to CVS files
in the init_db method when debug is True.

Changes to help debug unicode problems
bootstrapping: init_db(True) works correctly

appropriately (also from the csv dump)

FIXME: Recipes throw an exception if you try to get their repr. Some kind of
Unicode bug. Needs looking into.
