refactor($route): pull $route and friends into angular-route.js

$route, $routeParams and ngView have been pulled from core angular.js
to angular-route.js/ngRoute module.

This is was done to in order keep the core focused on most commonly
used functionality and allow community routers to be freely used
instead of $route service.

There is no need to panic, angular-route will keep on being supported
by the angular team.

Note: I'm intentionally not fixing tutorial links. Tutorial will need
bigger changes and those should be done when we update tutorial to
1.2.

BREAKING CHANGE: applications that use $route will now need to load
angular-route.js file and define dependency on ngRoute module.

Before:

```
...
<script src="angular.js"></script>
...
var myApp = angular.module('myApp', ['someOtherModule']);
...
```

After:

```
...
<script src="angular.js"></script>
<script src="angular-route.js"></script>
...
var myApp = angular.module('myApp', ['ngRoute', 'someOtherModule']);
...
```

Closes #2804
