Notify user about activation link using popups

As a New Comer I'd like to see popups instead of blocking dialogs so that I don't have to do extra clicks - I cannot change anything in the informative dialogs anyway

Acceptance Criteria:

• Given I'm registering a new account (via Dialog or separate Page), when I press final Sign Up button, I should see green non-blocking popup that says that activation link was sent to my email.
• Given any errors, the popup should be red. It should provide an ability to re-send the email again.
• Given I'm logging in (via Dialog or separate Page), if I'm not yet activated, I should be notified about that with error message. In the error message when I press to Send Activation Email I should see the aforementioned popup.
• The difference between Dialog and separate Page: the dialog should be closed when user asks to re-send activation link. In case of page - nothing should happen besides the green/red popup.
