[PATCH] Bug 327691 – URI-bar location persists after deletion

["Gene Z. Ragan" <diskzero mac com>]

Comrades,

This diff addresses the various state issues created when deleting a directory
or file.  The navigation arrows, path bar and bookmarks are all adjusted when a
file is deleted

I am not totally comfortable with nautilus-window-info having access to data structures that are 
located in the src directory.  I am not sure if this is an abstraction violation.  I didn't see
any other interfaces to update the path bar, but maybe I am missing it.  Suggestions are greatly 
welcomed.

Thanks!

Gene
