Mining test debug output, fixes to diff. adjustment and start of POW documentation ( #69 )
...
* Beginning to add a POW description, and some minor changes to mining testing, addition of further debug information to mining output.
* Many additions to create first draft of POW documentation
* Fixes to difficult adjustments by adding a MINIMUM_DIFFICULTY consensus value. Otherwise never adjusted above 1 due to flooring.

Apply new difficulty algo, remove configurable cuckoo size
...
Integrate the new difficulty calculation into the block chain
validation, the miner and tests. As the difficulty calculation
doesn't use varying Cuckoo sizes anymore and we narrowed down
reasonable final Cuckoo Cycle parameters, removed all Cuckoo
Cycle sizes from block headers.
Formalized easier Cuckoo Cycle sizes for testing (and possibly
testnet) by introducing a test mode in configuration. Updated
all tests.

PoW only ever needs the block header, full block unnecessary.

Chain logic to support multiple forks, select the most worked fork as the head. Significantly simplified from the original direction as it doesn't seem that explicitly materializing forks is necessary. Simple total difficulty accounting in block headers helping a lot there.

Removed need for a PowHeader. Directly checking serialization mode in block header serialization instead.

Block headers maintain total difficulty up to previous. Changed all references of target to difficulty to stay consistent. Ported retargeting algo to use difficulty as well.

Minor API change to PoW verify, to use the size provided by the block header by default.

Block header needs its own deserialization. Fixed pow verify to use the block target.

Block now uses the new Target type. Consensus next_target calculation adjusting every block based on deviation and increasing Cuckoo size gradually. Block time of a minute until we learn more from mining ecosystem, so enough PoW attempts can be made even on CPUs.

p2p module getting close to first integration test allowing 2 peers to connect. Fleshed out handshake and protocol use. Fixed most errors, just need to make the borrow checker happy.
