• Replaced the built-in Lua implementation of os.clock() so it doesn't stop working after the program has been running for more than 24 days (which caused asychronous prompt filtering to stop working). As a side effect, the new os.clock() has microsecond precision instead of millisecond precision.
• Fixed coroutine throttling. It was meant to prevent running more than once per 5 seconds, but accidentally forced running every 5 seconds, even if the coroutine was registered to run less often.
