SelectDateWidget should have possibility to have more custom configurations
It is possible to add some extra configurations to SelectDateWidget constructor.
There was a need for me to use custom "empty" value for each field and custom <select> order, not assigned with settings.
And that's what was done. I'm attouching my own version of forms.extras.widgets module.
It just differs in described above functionality and completely backward-compatible.
Also current v1.3 code was looking dirty for me, so most such places were rewritten. Hope this version will get into repository
