Tailored idea status email templates Merged

Just getting into focusing on more meaningful communications to our ideas portal users and have identified that it would be great to be able to configure different templates for different statuses of ideas, so that the appropriate tone can be communicated with the users. 

If we are not going to progress and idea, we don't want to send them a template that says, "Great news, your idea has been rejected". Equally, when we ship an idea, we would like to include additional information including links for the user to give us a review. Obviously we would not want to send this out until we have done something that the user can actually repond to.
