Fixing a crash in a file-name handling routine.  This bug was exposed as a result of running VisIt on windows with an empty VISITUSERHOME environment variable.  If called with an empty directory argument, the method in FileFunctions.C will crash because it does directory.substr(directory.size() - 1).  To fix this, I check explicitely for the empty 'directory' string and return failure in that case.
