Issue about localization 

it seems that the line 97 in tpl_functions.php:

```
            if(@file_exists(DOKU_TPLINC.'lang/'. $conf['lang'].'/nonidebar.txt')) {
```

should be:

```
            if(@file_exists(DOKU_TPLINC.'lang/'. $conf['lang'].'/nosidebar.txt')) {
```

so that localization would be properly applied.
