Update view.blade.php (Proposition)

I think it will be better to not force the user to provide a page title, because we can also use the title for most situations.

So something like:
```php
@section('title')
 {{ !empty($post->page_title) ? $post->page_title : 'Blog &middot; '.$post->title }}
@endsection 
```
instead of:

```php
@section('title')
 {{ $post->page_title }}
@endsection 
```
should be appreciate :)
