If someone attempts to construct an STAccount with something other than 160 bits the constructor now throws. Since an STAccount now enforces that it always stores exactly 160 bits, we use a fixed-sized uint160 for the storage, replacing a variable sized STBlob. In order to leave the ledger and wire formats unaffected, the STAccount still serializes and deserializes itself as though it were variable length.
