max_year base case bug fixed. ezic:localtime/1 works.

the final flatzone for every Zone should end at "current" for every *_to time. This is inaccurate, but accuracy is only guaranteed up to ?MAX_YEAR (=2500 by default).
that working, I fleshed out the few methods required to get ezic:utc_to_localtime/2 working, thus localtime/1 working. I've only tested localtime/1 at this point.
additionally, mnesia appears to have its data corrupted every time I stop and start a node. I've got to read up on working with mnesia; it's not behaving as I would expect.
