Deprecate applications DocName (keep only Name)

I am in favor of deprecating (and then removing) SetDocName. Any opinions on that?

It seems a bit redundant to me and I think it contributes to user confusion. In fact, out of the 106 OTB applications, only 40 have doc names different than the name (ignoring case and spaces).

For the 66 other applications app.GetName().lower() == app.GetDocName().lower().replace(" ", "") is True, so the doc name is completely redundant.
