ngRoute support for an array of paths.

ngRoute should support an array of paths that are going to use the same route.

So instead of doing this: 
```javascript
route = {...); 

$routeProvider
.when('/foo', route)
.when('/bar', route)
.when('/baz', route)
```

You could do this:
```javascript
$routeProvider.when(['/foo', '/bar', '/baz'], {...});
```
