Title: Allow enabling pjax without actually using pushState

This is another way to degrade gracefully on bowsers that do not support pushState.

In this mode, PJAX updates the dom with AJAX, but does NOT change the URL via pushState.

This works on IE 8.

This is how I'm using this in my application:
```javascript
if (!$.support.pjax)
$.pjax.enableWithoutPushState();
```
