Passing Index to #ic-tab does not initialize properly

[rtablada]

When passing a custom index to ic-tab components, the tabs list does not initialize as expected.
Clicking on a tab does update the property to the custom index, but no tab is selected by default.

Code modification of example:

  {{#ic-tabs selected-index=food}}
    {{#ic-tab-list}}
      {{#ic-tab index="hamburger"}}Hamburger{{/ic-tab}}
      {{#ic-tab index="noodles"}}Noodles{{/ic-tab}}
      {{#ic-tab index="toast"}}Toast{{/ic-tab}}
    {{/ic-tab-list}}

    {{#ic-tab-panel}}
      <h2>Hamburger</h2>
      <p>

  {{/ic-tabs}}

  App.ApplicationController = Ember.Controller.extend({
    queryParams: ['country', 'food'],
    country: 0,
    food: 'hamburger'
  });

@rpflorence is there any plan on continuing development of ic-tabs? And would you be interested in allowing custom string indexes for better query param urls?
