Official release Synology DSM 7 and Java8

[retraite]

Thank you for making the download available. I'm happy to report that Minimserver is now running again on dsm7. For the sake of completeness, I should perhaps note that when I tried to download it using the Firefox browser, I got the error message "Not allowed: https://minimworld.com/download-server.p...mv7_server".
There was, however no problem with Chrome or Edge.
I very much appreciate the effort you have put in on this.
