Adding a friend
---------------
Alice adds Bob to her friend list by adding his 32 byte public key (client_id) to her friend list.
2 cases:
case 1: Alice adds the public key of Bob, then Bob waits for Alice to attempt to connect to him.
case 2: Bob and Alice add their respective public keys to their friend lists at the same time.
case 1:
Alice sends an onion data (see: Prevent_tracking.txt) packet to Bob with the encrypted part containing the friend request like so:

If Alice is already in Bob's friend list: case 2
If Alice is not in Bob's friend list and the nospam is good: Bob is prompt to add Alice and is shown the message from her.
If Bob accepts Alice friend request he adds her public key to his friend list.

case 2:
Bob and Alice both have the others public key in their friend list, they are ready for the next step: Connecting to an already added friend
In the next step only crypto_box() is used for encryption and only crypto_box_open() for decryption (just like in the last step.)
