[gtk+] Clean up code to use the model directly

[Benjamin Otte <otte src gnome org>]

commit 3e385ffd077d5e8f888a2688642b90a0cbe75de8
Author: Benjamin Otte <otte gnome org>

    Clean up code to use the model directly
    
    A lot of code special cases accesses to the tree view for the different
    browse modes, which was previously necessary, because the models were
    different. Now that they are identical in the first columns, there is no
    such need anymore, and the functions don't need to be special cased.
