Fixes for new plugin and missing _ in $row within the helper file.

Tony - this is still not right.  What we need is

```php
<div class="jev_version">
<?php echo JText::sprintf('JEV_CURRENT_VERSION') .substr($version->getShortVersion(), 1); ?>
</div>
```

with 
```
JEV_CURRENT_VERSION="<span class='update_text'>You are currently on </span><span class="update_cur_ver">version : %s</span>"
```
