Upgrade/emberjs 1.13.2

[peec]

This PR will upgrade the ember version to 1.13.2 and also include changes to make paper compatible with 1.13.2.

Specifically this is done:

• Change to 1.13.2 of emberjs.

• The use of nearestOfType (paper-sidenav-toggle component) does not seem to work in 1.13.2. Instead a global event bus is used here. The event bus can come handy for other components as well. The event bus principle is explained quite nicely here. As of such one can now trigger from any component:

      paperEventBus: Ember.inject.service('paper-eventbus'),
      someAction: function () {
          this.get("paperEventBus").publish('paper:toggle-sidenav');
          // or 
          this.get("paperEventBus").publish('paper:expand-sidenav'); 
      }

  Obviously this event-bus is global, so it should only be used for global components. One could also make these events non-global by adding attribute to the event name. i.e. .publish('paper:toggle-sidenav-' + this.get("menuhandle")'). Though I do not think this is necessary for the sidenav component.
  EDIT: using parentView now.

• Updated {{#if template}} to respective {{#if hasBlock}}. ( With respective mixin to add support for pre 1.13.X releases).

• Updated ember-prism to 0.0.5.

@peec Please read emberjs/ember.js#11170

tl;dr

• Right now, we should use parentView
• In the future we may be doing stuff like this:

{{#paper-nav-container as |c|}}
  {{#c.paper-sidenav}} {{!-- sidenav here --}} {{/c.paper-sidenav}}
  {{#c.paper-content}} {{!-- content here --}} {{/c.paper-content}}
{{/paper-nav-container}}

Can you please refactor this PR to use parentView instead?

[miguelcobain]

Also, does using hasBlock break when using Ember 1.12?
Check #86.

@miguelcobain

I have now done the following:

• hasBlock: Created backwards compatible mixin so it doesn't break pre - 1.13.X releases.
• Removed service principle from commits and added support for parentView
• Upgraded to 1.13.3.

[miguelcobain]

@peec I think nearestOfType works fine now.

Also, in the hasBlock computed property we could check for a "_super" hasBlock property. If that exists, use it, otherwise use template.

[peec]

@miguelcobain

Good idea, I tested with nearestOfType and it works fine now.

Added:

• nearestOfType support again
• Check if hasBlock exist, if it does use it otherwise use this.get("template")

[miguelcobain]

Please remove app/services/paper-eventbus.js.

Thanks @peec!

I opted to keep ember 1.12 for now. That should affect people's projects, because ember-paper is now compatible with 1.13 as well.

When we move to ember-cli 1.13.1 we use its ember version.
