Zepto compatible

[fedeisas]

Is there any way we can use Zepto as a replacemente of jQLite just as we use jQuery? So that angular.element works seamlessly with both libraries?

I'm thinking this could be useful to serve Zepto to modern/mobile browsers and jQuery for older ones.

Does that makes any sense?

Thanks.

Based on discussion in #3350 it is not going to happen.
