Sharing passwords about passy

[GleammerRay]

Great idea, I believe it could be possible to create shared users. This would work by storing other users passwords in an encrypted file per user.

For each user added, their passwords should be displayed just like all the other passwords, but perhaps with some small indicator icon next to their icon. When a user decides to create a new password, they can choose whether to store the password in their account or to one of the shared users. These shared passwords will look and work just like any other passwords.

For synchronization to work, multi-account synchronization can be implemented. It could work by synchronizing multiple accounts one by one (doing them all at once would be complicated, since they all have different decryption keys, and the client-host authentication is also different per account).

This is the first step towards shared accounts, as Glare synchronization layer provides a powerful and secure RESTful API.

I have decided that shared accounts would be unnecessarily complicated to use and manage. I believe that sharing singular entries is a better convenience. This way, the sharing user may generate a connection QR code (and an IP address) that the other user can then scan to receive that entry from them.
