Help settings not accessed

Nasty bug in the chunk. The help settings are invoked using placeholder tags, not settings tags. Needs to be
``[[[[++quickbar.help:is=`1`:then=`++quickbar.helplink:notempty=`<li class="help"><a href="[[++quickbar.helplink]]" target="[[++quickbar.helptarget]]">Help</a></li>`]]]]

```
```
