Encrypt with senders public key

[ilyakatz]

I think it would be a good idea to encrypt emails with senders public key for any email that is sent encrypted. This way the sender will be able to decrypt sent email (an equivalent of the sent folder in whatever smtp provider that is used). So, for example

If an email is sent with gpg encrypt: true, it would automatically add sender's key to the key argument. This perhaps make more sense in ActiveMailer and then you could have a global setting

# this will be the default even if it is not provided
config.action_mailer.gpg_encrypt_sender = false 

or

config.action_mailer.gpg_encrypt_sender = { 
  keys: { 
   '[email protected]' => support_key,
   '[email protected]' => tech_key 
  }
} 

I'd be happy to give it a try but I wanted to run it past you before I starting coding away. What do you think?
