Allow one-time skipping of activation-related emails for new users.

This is useful for special cases where you want to manage the emails yourself (but still want the default config to send the emails)

Activation Needed Example:

special_user = User.new
special_user.skip_activation_needed_email = true
special_user.save! # activation needed email does not get sent

Activation Success Example:

special_user = User.find(special_user_id)
special_user.skip_activation_success_email = true
special_user.activate! # activation success email does not get sent
