[Cin] Website & Server Improvements

Hi guys. Some maintenance work was done on the server last night to improve load times and performance. The download speed for downloading builds and packages has been drastically increased. In addition, the website is mirrored via Cloudflare to provide faster access worldwide. This shortens the distance from the user to the website as far as static content is concerned. For a short time the changes can lead to slight interference. If problems should be observed in the long run, please report to me. Have fun with Cinelerra GG. Sam --
