Start Forge Multipart support
Attempted to implement ForgeMultipart carriages. They still don't work.
IT LIIIIIVES!!!! FMP carriages are done. They work like frame carriages.
Fully finished multipart carriages
Fix types so that it works outside of dev environments
Separated anonymous class into its own file, hopefully it shouldn't be hidden from Forge/MCP's renaming now
Fixed a sidedness bug. Did I mention I hate those?
