Fixes bug #48

  - Removed debugging Exception that is thrown if template variables
    loops over an empty array or null (see example/i18n/index.php for
    testing).
  - Cleaned up trailing spaces (and CRLF) of committing files.
  - Added smart to make i18n example work out of the box on Linux
    machines as well.
