[gtk+/multiroot-filechooser: 4/30] Make the local_only property wrap root_uri.

[Federico Mena Quintero <federico src gnome org>]

commit 2d8588a2e3de657fb282568fde84377972443644
Author: Christian Hammond <chipx86 chipx86 com>
Date:   Tue Feb 2 03:43:49 2010 -0800

    Make the local_only property wrap root_uri.
    
    Root URI and Local Only properties are very similar, so this change combines
    them into one concept. A root URI of "file://" is now the same as the old
    Local Only. The old Local Only property remains, and we may even want to keep
    it around indefinitely, but it just simply wraps a root URI of "file://".
    
    The set_local_only and set_root_uri functions have been merged, and improved
    logic for setting the current folder on root URI/local-only property changes
    has been added.
