BlockchainDB unit tests, lmdb linker flag
Some BlockchainDB unit testing fleshed out (and working), rudimentary
linker flag for lmdb in CMakeLists, but should probably be done
"correctly" at some point (find it on whatever system you're building on
and all that jazz).

update for rebase (warptangent 2015-01-04)
  fix conflicts with upstream CMakeLists.txt files
