• Added refuel program when generator upgrade is installed (thanks Vexatos).
• Added update check (can be disabled in config).
• Made files opened in write mode seekable where possible, to better mimic standard Lua's I/O.
• Computer cases and server racks now also accept power directly (i.e. for simple builds the Power Converter is no longer required).
• Reworked Switches (previously Routers) so that messages will always give the actual sender's address instead of the address of the last Switch they passed through.
• Switches will only forward one packet every five ticks now, and have a limited queue of size twenty. Latency and network congestion, check.
