Active.Formats.Date fix
Here is the corrected code for Active.Formats.Date class. It fixes the bug where the months were offset by 1 when formatted as number ('m' and 'mm' tokens). It also allows to specify error value (was ignored previously) so you can push the non-dates on top or bottom when sorted.
