div surround status-bar-view and add title to link

Adding a div provides better separation, easier stylesheet selection, and more consistency with other status-bar elements. Also added a title to the link for a hover tooltip and for a unique stylesheet attribute.
If you do something like ` @a href: '#', class: 'inline-block', outlet: 'grammarLink` here, then down below you can just do:

```coffee
@grammarLink.text(grammarName)
```

instead of 

```coffee
@children().text(grammarName)
```
