Title: Make blockHelp() do nothing if no text is passed

The use case would be something like this:

```php
blockHelp(empty($news)?null:'') ?>
```

Basically, I'd like to use the ternary operator in the blockHelp() call to only show an image if I have the data for it. And if I don't, I don't want the p tag created for blockHelp.
