hardfork at block 100,000
The verify storage proof code is incorrect, missing the case where the final segment was the correct length. This can be corrected with a hardfork that has been scheduled for block 100,000.
We may want to consider anything else that might be on the hardfork wishlist since we're doing another hardfork.
All v1.0.0+ versions will have the hardfork code, seems reasonable to me.
