very, VERY primitive blockchain converter
hard-coded config folder, hard-coded BlockchainDB subclass. Needs finessing, but should be testable this way. update for rebase (warptangent 2015-01-04) fix conflicts with upstream CMakeLists.txt files src/CMakeLists.txt (edit original commit) src/blockchain_converter/CMakeLists.txt (add)
