#38 OpenWB doesn't manage years with 53 weeks

[ogechter]

Hello,

Some years, like 2004, are made with 53 weeks and not 52.
In Open Workbench, this details was forgotten and the Week 1 of
2005 begin... in december 2004.
So, all the week numbers are wrong and it's not possible to use this
device during a full year.

Week numbering is defined by ISO 8601 standard.

Week number 1 is the week that contains the first Thursday
of the year, or (this is equivalent), the week that contains
the 4th of January.

OWB does not implement this correctly.

In 2005, week number 1 begins the 3rd of January, but OWB
considers this to be week number 2, and all following weeks
are wrong by 1.
