GtkFileChooserWidget with only extra "Name" line in SAVE mode

[Yury Alyaev <mutab0r rambler ru>]

Hello all,

I'm wondering if there is a mean to make GtkFileChooserWidget in SAVE 
mode to look like in OPEN mode with only additional Name: + entry line 
above the stuff common in SAVE and OPEN modes. That is I want to remove 
"Save in folder:" + combo + expander "Browse for other folder". I have 
not found the straightforward way to do this. Only hacks?

Regards,
Yury.
