Update path verification related to source directories.
    
    - Previously, the tcar_checkRepoDirSource function was used to verify
      the path information based in the repository not the workplace. This
      function prevented tcar script from executing its commands outside
      the repository directory structure, which make impossible to run
      tcar scripts commands in the repository's workplace.
    
      Now, to make the execution of tcar commands possible in repository's
      workplace, this update changes the path verification function from
      tcar_checkRepoDirSource to tcar_checkWorkDirSource function.
    
    - Removes tcar_checkRepoDirSource function from tcar scripts. The
      tcar_checkWorkDirSource function is used instead.
    
    - Previously, the tcar_checkWorkDirSource function didn't remove
      dot-slash (./) characters from the final location. This made tcar
      script to print paths like 'Scripts/./Locales/es_ES/tcar.sh.po'.
      This update removes dot-slash characters from final location to make
      tcar script to print paths like 'Scripts/Locales/es_ES/tcar.sh.po'.
