Error working with file-paths which contains whitespaces

The _gjslint_ _python_ tool is executed via command-line, and the separator of the file-paths and the options is the whitespace character. Therefore, when a path contains a whitespace, the _gjslint_ tool divides it in two different ones.

If these paths are well-formed the _gjslint_ ignores them, but if at least one of them starts with an invalid character, the tool reports an error.

Examples:
*  Path: ``/usr/home/project name/test``
   * Command line: ``gjslint /usr/home/project name/test``
   * Results:
      * ``/usr/home/project`` ok
      * ``name/test`` ok
*  Path: ``/usr/home/project (name)/test``
   * Command line: ``gjslint /usr/home/project (name)/test``
   * Results:
      * ``/usr/home/project``: ok
      * ``(name)/test``: error

The solution is to wrap the path between double quotes when it contains whitespaces:
*  Path: ``/usr/home/project (name)/test``
   * Command line: ``gjslint "/usr/home/project (name)/test"``
   * Results:
      * ``/usr/home/projec (name)/test``: ok
