Browse fixes: Made parent directory entry always the top item. Hide parent entry if already at the root directory.  Fixed VLC 2.x not showing parent entry when at the root of a drive on Windows (parent would be drive list). The current directory is now displayed in normalized form (with resolved .. parents).
Fixed directory being changed back to home when a selected directory is not accessible. The parent directory is opened instead. Updated toast error message.
Added check for invalid xml when finished loading directory. This prevents "no connection" errors when the connection is active but cannot get read access
