Fixed display of unique path of parent directory in 'Directory Listing'
window per AUT-750 and AUT-753.
Removed inner classes ShortNameVisitor and GetPathVisitor from
ContentUtils as well as method 'getSystemPath()' per AUT-753. This
functionality has been replaced by use of Content.getUniquePath().

These changes in support of AUT-740 concerning KeywordSearch 'Advanced
Keyword Search Configuration' dialog box. Renamed 'Save As' button to
'Copy List'. Added cancel button. Altered logic so that when a copy list
operation is aborted, a dialog no longer pops up saying that the list was
saved.
Fixed log message typos.
