Migrating away from Sourceforge

[Jerome Leclanche]

Counting only the Wine numbers: The downloads from Sourceforge average
out 52k / week. At an average of 20 megabytes per download that's ~4
terabytes / month. It's a lot, but nothing out of the ordinary (about
$20 / month on DigitalOcean, for example).

Roughly 7k requests a day is something a cheap server can fairly easily handle.

I fully support this move and will gladly donate to help the server costs.
