Zodiac

Did a lot of work on Zodiac, rewrote most of Zodiac's SdDAL module. It it is annoying that I can get it to work, but only if I do something that exactly matches the "do not do this" section of the processor's manual. If I do what it says to do, data gets lost. Obviously I will not be releasing code that is wrong, even if it works... Let's hope this is easily resolvable.
