    Update render module from tcar script.
    
    - Previously, path verification was using the tcar_checkRepoDirSource
      function which points to TCAR_BASEDIR. This made the render module
      to consider the path provided in the command-line as a relative path
      inside the installed repository not the workplace. This made the
      script to fail because the path provided doesn't exist. This update
      changes the render module to use tcar_checkWorkDirSource function
      which points to TCAR_WORKDIR instead. This way, the render module
      looks inside the workplace, not the installed repository.
