Update game server certificates. This fixes the recent LOTRO connection errors.
In case anyone's curious, the next version of OneLauncher is 2.0. I'ts a huge upgrade over this version, but is still not ready yet. The latest stableish progress is always available to check out at https://github.com/JuneStepp/OneLauncher/tree/develop for the technically inclined. Just know that nothing's final, and breaking changes are still semi-frequent.
