Enable editing of account name

This is a feature request for the Authy mobile app.

It would be nice to be able to edit the account name after it’s already been set. In my case, I was setting up Authy for multiple accounts and realized later that I didn’t customize the account name during the setup process. So now the account names are all displaying the same name.

Here’s a screenshot to clarify: https://www.evernote.com/l/AAcewHhcpVtGVoiIbYRUP6LLJM2xttLcnJc
