Add enabled property to Exoplanets and Skybrowser module (#1945)

* Add enabled property to exoplanets and sky browser module

* Create assets for default settings and restructure assets into a components folder

* Update exoplanets data

* Set sky browser enabled to true per default and include hover circle asset

* Add name and description of hover circle, and used synced version of ring image
