Moved write_date column from website_hr_recruitment to hr, because it could be usefull
to have this column directly existing in the model. Other website-related columns remains
in the website module.
Also moved python file into a new models directory; also renamed the file. Please use
correct file name instead of finding a loosely-related file name.
