Breaking: the os_execute return codes are no longer normalized to Lua 5.3 output since that didn't work due to platform and version differences. Now it just returns the same results as the regular os.execute for the current platform/Lua version.
Fix: io_popen; the default mode should be "r"
Fix: io_popen; the default read pattern should be "*l" and nil should not be passed.
Fix: only initialize LuaLanes if not initialized already
Added: io_popen now also has the lines iterator (except for Puc Rio Lua 5.1 where it will not work due to c-boundary issues)
Added: run method, to simply run and wait for an async result while not blocking (this also is the default action when calling on the module table).
