Support for `template` not just `templateUrl`

Steps to reproduce

N/A

Expected behaviour

Would be nice to have a new rz-slider-tpl directive attribute instead/along with the current rz-slider-tpl-url. That would help folks using webpack to require their custom templates upfront as usual, without the need to lube up $templateCache upfront. So with something like this in a controller:

scope.tplt = require('./my_custom_slider_template.html');

… markup would look like this:

<rzslider rz-slider-tpl="{{ tplt }}" rz-slider-model="slider.value" rz-slider-options="slider.options">/rzslider>

Actual behaviour

Only rz-slider-tpl-url is supported.

Same case as @kevin-king here. I am using a temporary script tag with the slider template as shown in this example: https://jsfiddle.net/meu7ap6n/
