Emoncms.org email verification

Up until this point the emoncms.org registration process has not required email verification allowing pretty much any correctly formatted email address to be used when registering for a new account. In order to a have a minimum level of identity verification and ensure we have a way to contact account holders I have now added email verification to the register process.

For existing users a message will appear when logged in. Giving a chance to amend the recorded email address before requesting the email verification email:

New registration will result in an email verification email as part of the registering process.

This feature is also available currently in a development branch for the standard emoncms here and will be merged in to the master branch soon: https://github.com/emoncms/emoncms/tree/email_verification
