BREAKING CHANGE: All directives are now prefixed with `ion-`.
For any directive you use, add the ionic prefix.
For example, change this HTML:
```html
<tabs>
<tab title="home" href="/tab/home">
<content>Hello!</content>
</tab>
</tabs>
```
To this HTML:
```
<ion-tabs>
<ion-tab title="home" href="/tab/home">
<ion-content>Hello!</ion-content>
</ion-tab>
</ion-tabs>
```
`content` directive stores scroll in view page history.
The history is passed down through $viewContentLoaded event, which is
broadcasted by navView directive when it loads a page.
