    file: Correctly check for remoteness for speed tradeoffs
    
    When the thumbnailing and/or item counting preference is 'local-only',
    we need to know if a file is local or remote, and for this we use the
    nautilus_file_is_local() method.
    
    However, ever since the port from gnome-vfs to GIO, this method relies
    on g_file_is_native() instead of gnome_vfs_uri_is_local(), which are
    not the same thing. Quoting the GIO docs:
    
    > A native file is one expressed in the platform-native filename
    > format, e.g. "C:\Windows" or "/usr/bin/". This does not mean the
    > file is local, as it might be on a locally mounted remote filesystem.
    
    So, nautilus_file_is_local() is no longer telling us the truth. This
    means we may show thumbnails or item counts for natively-mounted remote
    locations when we are not supposed to.
    
    Instead, let's use the nautilus_file_is_remote() method, which relies
    on the G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE attribute (which was not
    implemented at the time of the GIO port).
