    Update centos-art.sh script.
    
     - Refactor code used to initialize module environments in cli
       function through cli_initModule function.
    
     - In order for cli_initModule function to be reusable it is necessary
       to define the MODULE_BASEDIR variable inside the most specific
       module's configuration file.
    
     - The value verification of TCAR_USER_EDITOR variable was removed
       from cli function. I didn't put in centos-art.conf either. So, be
       sure to put an existence text editor as value to this variable. By
       default, /bin/vi is being used.
