[1.12.2] 1.81.0

Changes from the last CC:Tweaked release

• Handle connection errors on websockets (Devilholk)
• Make require a little more consistent with PUC Lua, passing the required name to modules and improving error messages.
• Track how long each turtle action takes within the profiling tools
• Bump Cobalt version
  • Coroutines are no longer backed by threads, reducing overhead of coroutines.
  • Maximum stack depth is much larger (2^16 rather than 2^8)
  • Stack is no longer unwound when an unhandled error occurs, meaning debug.traceback can be used on dead coroutines.
• Reduce jar size by reducing how many extra files we bundle.
• Add term.nativePaletteColo(u)r (Lignum)
• Split colours.rgb8 into colours.packRGB and colours.unpackRGB (Lignum)
• Printers now only accept paper and ink, rather than any item
• Allow scrolling through the multishell tab bar, when lots of programs are running. (Wilma456)

Minor fixes

• Fix modems not being advanced when they should be
• Fix direction of some peripheral blocks not being set
• Strip \r from .readLine on binary handles.
• Websockets handle pings correctly
• Fix turtle peripherals becoming desynced on chunk unload.
• /computercraft table are now truncated correctly.
