Cleanup release area

This step should be performed after the website updates have been made as the download links change.

There should only be one release, the latest, in the release area. Any release that has been in the release area will be automatically copied to the archive. Older releases should be downloaded from the archive directly, not from the release area.

The releases need to clean up in two locations:

• Remove the newly released version from the dev area by removing the old release candidate directory. For the location see release candidate location
• Remove the non-current release from the release area by removing the old release directory. For the location see release location
