Moved utilities and audio examples

I have moved the utility programs (file_dump, replace_string, restore_files, remove_duplicates, dos_to_unix, and unix_to_dos) and the audio example files to their own project areas. The utility programs are now the Simple Command Line Utilities (http://sourceforge.net/projects/clutil) project and the audio examples are now the Command Line Audio (http://sourceforge.net/projects/claudio) project.
