Update blockchain utilities with portable bootstrap file format
Remove repeated coinbase tx in each exported block's data.

Add resume from last exported height to blockchain_export, making it the
default behavior when the file already exists.

Start reorganizing the utilities.

Various cleanup.

Update output, including referring to both height and block numbers as
zero-based instead of one-based. This better matches the block data,
rather than just some parts of the existing codebase.

Use smaller default batch sizes for importer when verifying, so progress
is saved more frequently.

Use small default batch size (1000) for importer on Windows, due to
current issue with big transaction sizes on LMDB.

Add blockchain_import utility
This imports to the blockchain database from an exported blockchain
file.

It can be used to bootstrap a new database or to add blocks to an
existing one.

Supports:
  - both the in-memory and LMDB implementations
  - optional: batching, verification, testnet

See help for usage.

Based on work by tomerkon.

Moved BlockchainDB into its own src/ subfolder
Ostensibly janitorial work, but should be more relevant later down the
line.  Things that depend on core cryptonote things (i.e.
    cryptonote_core) don't necessarily depend on BlockchainDB and thus
have no need to have BlockchainDB baked in with them.

Add compile-time support for both db implementations: in-memory and LMDB
Usage:

default is lmdb for blockchain branch:
$ make release

same as:
$ DATABASE=lmdb make release

for original in-memory implementation:
$ DATABASE=memory make release

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)
