[1.12.2] 1.80pr1.9

Changes from the last CC:Tweaked release

• Add German translation (Vexatos)
• Add .getCursorBlink to monitors and terminals.
• Allow sending binary messages with websockets.
• Extend fs and io APIs
  • io should now be largely compatible with PUC Lua's implementation (:read("n") is not currently supported).
  • Binary readable file handles now support .readLine
  • Binary file handles now support .seek(whence: string[, position:number]), taking the same arguments as PUC Lua's method.

Minor fixes

• Fix repeat program crashing when malformed rednet packets are received (gollark/osmarks)
• Reduce risk of deadlock when calling peripheral methods.
• Fix speakers being unable to play sounds.
