"Next" does not work when the navbar has dividers

[thiloplanz]

The "next" method does not work when there is a divider in the navbar between the
current tab and the next one.

For example

li: a(href="#tab5",data-toggle="tab") Tab5
li.divider-vertical
li: a(href="#tab6",data-toggle="tab") Tab6

Removing the divider makes the code work as expected.

Since dividers are part of the Bootstrap documentation and examples, this should probably be accounted for.

Ignore "Pull Request #46: Made 'shown' event compatable with both Twitter Bootstrap 2.3.2 and 3.0.0". My mistake while figuring out pull requests. I think everything is in order now. Sorry about that.
