Update manual_getActions.sh:
    
        - Introduce MANUAL_NAME variable. This variable stores manual's
          filename in lowercase (no path, just the name).
    
        - Use cli_getFilesList MANUAL_DIR and MANUAL_NAME to build the
          absolute path to manual's base file. Using cli_getFilesList we
          use find to find out the manual base file which let us use
          intermediate directory structures inbetween (e.g., to ilustrate
          the release information manuals are built for.) and also keep
          the name relation between manual directory and manual base
          filename.

        - Use cli_printActionPreamble to force MANUAL_BASEFILE
          verification.
