using eloquent's magic instead of datetime fields

Hey @formativ,

Great tutorial on using L4 to create a simple e-commerce site. While reading I thought why you didn't use Eloquent's "magic" methods instead of datetime fields (updated_at, created_at, deleted_at). Eloquent has ```$table->timestamps();```and ```$table->softDeletes``` that should be more "universal". How about using them?

Cheers!
