IE8 Support

[tomchiverton]

Steps to reproduce

1. open http://angular-slider.github.io/angularjs-slider/index.html in IE8

Expected behaviour

Works

Actual behaviour

Fails to fill in the template values or draw slider.
Logs "Node is undefined" in angular.min.js line 183

[tomchiverton]

Under older Angular's (v1.2) IE8 logs "Error: Unexpected call to method or property access" and does not draw the control, though the rest of the page is OK.

FireFox and Chromium are at least is happy after these changes, as is IE8.

You must use

<div rzslider class="rzslider" rz-slider-model="priceSlider"></div>

rzslider.js then needs to declare the directive like this (change restrict)

...
  return {
      restrict: 'AE',
      scope: {
...

I don't understand what you say, currently the directive doesn't use replace: true.

@ValentinH I thought it needed it. It doesn't. Incoming pull request.
