Small update

We just pushed a small maintenance update. This build includes the following:

• Upgraded our MonoGame-SDL2 branch to the latest code (FNA). This should fix a rendering issue that one user was having.

• Upgraded to the latest version of the Steam SDK. This just fixes an occasional bug that made the Steam avatars too big on Linux sometimes.

• Fixed the granting of Ladybug achievements. They were sometimes granting even if the Ladybug wasn't the piece that moved.

• Made the Online Games menu screen not flicker when it updates the list of games.
