Improve the blog post form
Here are few improvement that could be done for the blog post form :
- Author name should be hidden as it should be the name the user is connected with
- Delete state is confusing as the blog post is not created yet. It should be shown only when editing the post.
- Linking a media from the media-center to a blog post could be improved, but we have to see how much time it could take. For exemple "Image" is only for Image from the media center. Videos is for videos but also for other media type like PDF, which is a bit weird and hard to explain to the end-user.
