Fixes bug #48

Changes:
  - 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.

(sorry for the trailing diff, speedmax, looks like Git diff considers 2 different files, but the only change made in the tags.php file was the removal of lines:

```diff
134	 	 -        // Make debugging a bit easier
135	 	 -        if( ! is_array( $iteratable ) && ! $iteratable instanceof Traversable ) {
136	 	 -            $repr = (is_object( $iteratable ) ? '<class: ' . get_class( $iteratable ) . '>' : (string)$iteratable );
137	 	 -            throw new InvalidArgumentException("The for tag cannot iterate over the value: " . $repr);
138	 	 -        }
```

Hope that clarifies the need for this merge.

Thanks,
