- Fixed taint

Very difficult bug to find, a taint was being caused by wow client 8.1 and above, found the issue at the end and decided to bring the coordinates addon back to a more true to itself addon, thus fixing the taint by removing some features such as windows / popup drag and centering.

- Removed select window drag

- Removed select window centering

- Updated addon menu options to reflect changes

- Updated welcome message and addon menu home page

- Bumped version
