This is the first part of the API. It supports most of contacts, as well as the
journal. This PR also brings Monica to Laravel 5.5, as the API required it with
the new concept of resources. It needs to run `php artisan migrate` as well as
`php artisan passport:keys` to generate the access tokens needed for the API.
This is just causing too much headache, especially since I made the rookie mistake of not checking the max length of some entries when inserting the gift. That leads to errors in the decryption process.
In production, out of the thousands of gifts already entered, only 5 are not decryptable. I have no other choice than resetting these 5 rows. I'm really sorry about this.
If you do end up having problems running the migration in your own instance, you need to remove the rows that are un-decryptable in the Gifts table as well.
