This adds a (trivial) set for type bytes32. bytes32 is very commonly used for identifiers, since it is the result of a hash operation, and unlike uint256 doesn't have arithmetic operators.

Thanks!

I think we should change the name to Bytes32Set, since bytes is the type for dynamic length byte arrays in Solidity. (Note that UintSet doesn't have this problem because uint and uint256 are synonyms.)
