Secret key adding to the key chain

[FloatingLizard]

A setting that allows the user to save the secret paraphrase is saving automatically to the key chain on MACOS Sierra. That means that we have to uncheck every time we enter the password, and if we forgot to uncheck the box. We have to delete the password from the key chain.

This is something that has to be done in the GPG-agent layer . .

Parking this issue for now.
