Added ionModalView

[joshdholtz]

Makes adding a modal a little more Ionic Framework-y - Closes #1667

Anything thoughts, comments, or critiques are welcome - this is my first JS contribution to the world :)

OLD WAY

<div class="modal">
  <ion-content>
    Josh is a pretty cool guy
  </ion-content>
</div>

NEW WAY

<ion-modal-view>
  <ion-content>
    Josh is a pretty cool guy
  </ion-content>
</ion-modal-view>

OR OTHER NEW WAY

<div ion-modal-view>
  <ion-content>
    Josh is a pretty cool guy
  </ion-content>
</div>

I'm on the fence about this. While it's a solution to #1667, I'm not sure it's the "proper" solution to that issue.

With that, while it does feel more "ionic-ey", I'm not sure what the benefit is. I'd like to add this, but I'd want to see more baked in functionality.

@ajoslin, maybe this could be extended to interact with the $ionicModal service in a similar way to how we discussed the popover approach.

This is separate from #1667. This is just making it so we don't have to write <div class="modal">.

I like it.

@ajoslin Quick question for you. Is there a reason this PR wasn't merged and my code was duplicated (without the tests) in that commit? Just curious on what the policy for Ionic pull requests are. Thanks!

[ajoslin]

My bad Josh ... I got carried away with doing other modal features and additions at the same time and forgot to pull your version down.

[ajoslin]

The norm is for us to merge other code. If it's right, I try as much as possible to pull down contributors' code, change a couple of lines if needed, and merge theirs.

If you look in the commit log, you can see three PRs that were merged Monday. https://github.com/driftyco/ionic/commits/master
