contacts: prevent duplicate contact creation 
When adding contacts from an envelope view, its hash/id/key was a random
Uuidv4, so it was always possible to add a contact again and again with
no limits. Now, the id is calculated from the hash of the email address
and display name, preventing duplicate additions.

Note that the hash algorithm is not supposed to be stable across
versions, meaning that in the future the same contact might have a
different hash. This means a more sophisticated method for
detecting/disallowing dupes must eventually be introduced.

Example: Parsing bytes into an Envelope

An Envelope represents the information you can get from an email's headers and body structure. Addresses in To, From fields etc are parsed into Address types.

use melib::{Attachment, Envelope};

let raw_mail = r#"From: "some name" <some@example.com>
To: "me" <myself@example.com>
Cc:
Subject: =?utf-8?Q?gratuitously_encoded_subject?=
Message-ID: <h2g7f.z0gy2pgaen5m@example.com>
MIME-Version: 1.0
Content-Type: multipart/mixed; charset="utf-8";
 boundary="bzz_bzz__bzz__"

This is a MIME formatted message with attachments. Use a MIME-compliant client to view it properly.
--bzz_bzz__bzz__

hello world.
