Start cleanup into ripple_data, split out some hash_value() instances Tidy up CBigNum into ripple_data, moving definitions to .cpp Split and clean up base58 stuff Remove unused files from VS2012 project Clean up some bignum stuff and remove unused files Partial cleanup of RFC1751 Enormous cleanup with RippleAddress and related, into ripple_data Remove unused VS project files Move ECIES stuff into CKey
