Enhancements for Email Management in Bitwarden

[jetlime]

Code Contribution Proposal

After using Bitwarden for a few weeks, I've experienced some pain points related to the email attribute that I would like to address. I would therefore like to propose some changes to the bitwarden client:

• Multiple Email Support: Allow each identity object to link a list of emails instead of just one. This would enable Bitwarden to suggest a selection of emails when filling out forms. The majority of users have a set of various emails and not just one.

• Username Dropdown Menu: When creating new login objects in the Bitwarden client, the username often corresponds to one of the emails in the identity object. However, the UI does not propose to autocomplete the field with an already used username or an email linked in the users identity object. It would be nice if the client provided a dropdown menu with previously used usernames/emails and the emails defined in the identity object.
