Do not stop propagation of all click events in the document.

I think that this is a bug as propagation of all click events in the document is stopped - I don't see the purpose of such wide application of stopping propagation.

The unwanted effect of that is disabling the Command + Click behavior in Firefox that lots of users use. 

Simple repro scenario: 
1. Open Firefox
2. Go to http://twitter.github.io/bootstrap/
3. Try Command + Click on any of the link (normally is opens URL in the new tab).
