add childSelector option

[smistry-toushay]

Ember.js adds script tags in between elements.

The childSelector option allows the swipes element children to be filtered using a selector.

This addition doesn't support all browsers that Swipe claims to support. And I don't see a good way to do this without querySelectorAll() or a selector engine like jQuery

Good point, another option would be using a element filter callback. What do you think?

This only means dropping IE7 support, which is really not much used anyway.. but I get that this would be a regression.

Would love to see the ability of using a childSelector implemented. This has more use cases than merely resolving conflicts with Ember.js script tags. :thumbsup:
