CAPX-17 - New Mapping Button

# Ready for review
* Added create new mapping button and help text. 
* Broke out pages into their own file.
* Added button class to links so that they look like a button.
Thanks for this heads up but we have a special case to use this. 

We use:

This module hooks into our custom modules and ties them into the update status notifications using github's api and release system.
