worked on cleaning up newscript, adding features

* newscript.conf :
    - added option: show-qualified-filenames
    - added section: nterpreters-data
    - added interpreter: perl
    - added interpreter: ruby
    - added alias: pl->perl
    - added alias: rb->ruby
    - changed aliases section name to interpreter-aliases

* newscript :
    - added get_statusmsg_filename() : returns either qualified or relative filename based on config
    - added -h flag to show help (same as --help)
    - added date string and timestamp of last file edit for version information.
    - added interpreters-data config section to allow adding header data (i.e. <?php) to script files.
    - implemented option show-qualified-filenames
    - implemented qualified filenames with readlink instead of realpath as realpath fails on a non-existing file.
    - updated version string to 1.2
    - updated several commands to use the FQ filename instead of relative.
    - misc code reorganization
    - misc code cleanup
