mergeoperator name not null terminated

This looks related to

#21

I'm trying out the merge operator stuff, and found that if I don't end the returned string from Name with \000 the log file shows

Instead of just

Options.merge_operator: bitsetMergeOperator

Will be fixed in #96

@tecbot any plans on merging #96 soon? It also breaks the output of the sst_dump tool from rocksdb.

This is fixed now because of #125 (can't close issues though)
