Customize customer Sign up notification

When you have the configuration to enable customers to create their own accounts on the JSD project, the customers can use the Sign-up option, which will trigger the following email to complete the process:

"Almost done!

Follow the link below to finish signing up to Test Service Desk. For security, don't share this link with anyone."

This feature request is to allow the customisation of this notification because it would be great to have the ability to edit all of the other customer notifications, to use a similar "tone" and "voice" to that which is used on others customer notifications, and to be able to "brand" the email, to include logo, etc.
