CHUI-778 (Saving preferences updates text in all open message panels in conversation floater to show as old messages) Now changing the log/transcripts file location actually moves the files to the new location.

Also a fix was made so that if the user changed the log/transcripts path then after pressing the Preferences 'OK' button the new location will be saved to the corresponding .xml file.
