tcp connections for the internet card; reworked Lua bootstrapping a lot, now using package module where possible, and not injecting our custom modules into the global namespace by default. this WILL BREAK STUFF but if so it should be relatively simple to fix - just put a `local <x> = require("<x>")` on top of the borked script; renamed http lib to internet since it now also contains util methods for working on tcp sockets (wraps them as a [buffered] stream). more breaking. just rename all http references to internet and you're good.
