Update launcher to work with latest clients:

- NO dev mode anymore. A valid certificate is ALWAYS required.
- NO Arctium server connection. But do not rename things, thanks.
- NO other features than connecting to servers with valid certificates attached.
  Means: NO mod loading or dev mode. For that use our full-featured launcher at https://arctium.io
- NO binary releases.
- Only modern versions (all branches) are supported.

What you can still do:
- Launch modern game clients and connect to servers with a valid certificate attached.
- Specify custom version and cdns URLs to be able to launch older clients or data from your own CDN.
