Add a new flag to bypass two step authentication for subscribe/unsubscribe to pad

[mani89]

Hi, I would like to add a flag called 'ActivationEmailRequired' that we could set up in the settings.json. If the flag is set to 'No', for subscribing and unsubscribing to a pad, etherpad will not send an email with an activation link but directly subscribes the user to pad upon entering the email address and hitting the subscribe button. Shall I implement this feature?

Thanks!

Yes! Please.

@mani89 sounds good, go for it :)

I set this as enhancement but it might actually be a legal requirement to verify an email address prior to sending just to avoid spamming... I think it's required...
