Add temperature control. - Split out console stuff to cons.[ch]. Set up stdio so we can use printf etc. - Use \r\n as the line terminator consistently. - Add OWGetTemp to get temperatures from a device. - Load/save settings in EEPROM, defaults loaded from flash. Nearly feature complete except you can't edit ROM IDs without a programming tool :) (To be fixed) Needs more testing.
