HSA Booker nga g4dget

This add-on extends the website of the Hochschulsport Augsburg hsa.sport.uni-augsburg.de .
When booking a course, the extension can automatically fill out all user data in the booking form and submit the form, thereby helping the user save time during the booking process.
The add-on also allows marking individual courses. When an "Arm"-button on the website is pressed, the add-on will refresh the site until the course becomes bookable, at which point the add-on will automatically book the course.
