AbiathRPC - Level creation message size

While testing AbiathRPC's new ability to replicate newly created levels, I found that the client "received no meaningful response" from the method call that sent the level's contents to the server. I recalled that this had also happened when downloading the initial levels from the server, I remembered that I need to adjust the MaxReceivedMessageSize on the server end as well to allow it to handle the big packages that include full levels. With that done, the crash went away.
