Pop-up Emotes

1.3.4 & 1.3.5 Fix crash on client when disconnecting when uploading emote pack

1.3.2 & 1.3.3 Network optimization: Made the server and client send emote pack chunks in packets per tick instead of all at once. Now you can specify the limit of packets per tick sent or check the "Low Network Usage" option if your network bandwidth is small and you are not sure what limit to set. Available for both the server and client, defaults to 5 Megabytes/sec (8 packets per tick).

Added allowCustomPacks in the server config. Added lowNetworkUsage and maxPacketsPerTick to server and client configs. Added isEnabled to the client config screen (disables/enables the mod). Added maxPacketsPerTickPerPlayer to the server config.
