Title: change unstyled button attribute selector

I screwed up the last pull request, hopefully I get this one right.

This change prevents styles from breaking for unstyled buttons when classes do not *start* with 'btn btn-'. For example, without this change, this breaks:

```

```

Emberjs appends the 'ember-view' class to anchors in certain circumstances, which breaks styling. This new selector checks that the string is somewhere in the classes attribute but not necessarily at the beginning of the string.
