Included empty-string mapping keys in the storage variables.
This was done by relaxing the SHA3 filter in
contract_state. Before, only byte sequences longer than 32 bytes were accepted as SHA3 input. However, empty-string mapping keys produce SHA3("" || slot), therefore yielding a hash input of exactly 32 bytes.If the stricter length check was necessary to filter out false positives, let me know.
Resolves #34.
