Small patch, no gameplay changes.

If your connection is slow or flaky, the game could silently fail to upload your armies and match results. The uploads were too big and gave up after 4 seconds without ever retrying. We spotted it in the telemetry: one player's armies were reaching the pool while his match results never arrived, not once.

Fixed three ways: uploads are now about a fifth of the size, they get proper time to finish, and anything that still fails is saved and sent again later.
