Integrate BlockchainDB into cryptonote_core

Browse Source 
Probably needs more looking at -- lot of things were done...in a rushed
sort of way.  That said, it all builds and *should* be at least
testable.

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

  src/CMakeLists.txt (remove edits from original commit)
  tests/CMakeLists.txt (remove edits from original commit)
  src/cryptonote_core/CMakeLists.txt (edit)
  - use blockchain db .cpp and .h files
  - add LMDB_LIBRARIES
