Add paper-card title components

[baileymiller182]

Adds a few components to expand potential layouts of paper-card by providing analogs of the card title components found in Angular Material (https://material.angularjs.org/latest/demo/card):

• paper-card-title: Can be used in place of, or in conjunction with, paper-card-content to display card title text and images.
• paper-card-title-text: Displays some title text.
• paper-card-title-media: Displays a title image in the upper right corner of the card.

Example:

{{#paper-card class="card-lg-media-demo"}}
  {{#paper-card-title}}
    {{#paper-card-title-text}}
      <h2>Paracosm</h2>
      <p>The titles of Washed Out's breakthrough song and the first single from Paracosm share the...</p>
    {{/paper-card-title-text}}
    {{#paper-card-title-media}}
      <img class="md-media-lg" src="washedout.png">
    {{/paper-card-title-media}}
  {{/paper-card-title}}
  <div class="md-actions" layout="row" layout-align="end center">
    {{#paper-button}}Action 1{{/paper-button}}
    {{#paper-button}}Action 2{{/paper-button}}
  </div>
{{/paper-card}}

Would produce the following (from updated docs)

Looks good, @baileymiller182

We just need to update the template snippet at tests/dummy/app/templates/card.hbs and add a changelog entry.

Can you please do it?

[baileymiller182]

@miguelcobain Sure, this is done.

@baileymiller182 0.2.11 is released. The changelog entry would have to be under a #master version, for example.
