Unable to join servers with large plugin scripts

[IntelOrca]

Currently all scripts are sent uncompressed in a single packet. If the total data size of the packet is larger than 64 KiB, then it will send the packet incorrectly.

• The packets need to be broken down into chunks like how the map is sent.
• The scripts should probably be compressed.
• There should be some error messages when packet exceeds the maximum size.
