Zahary Karadjov 6a35d3584d Automate the creation of the network metadata files
With these changes, running a simulation is very close to running
an actual testnet. Some checks have been added in the client to
make sure you are not connecting to an incompatible network (e.g.
a network running with a different number of shards).

Dustin Brody f36c2d86dc begin 0.5.0 spec update (#179)
* begin 0.5.0 spec update: parent_root -> previous_block_root, BeaconState.justified_epoch -> BeaconState.current_justified_epoch, DOMAIN_PROPOSAL -> DOMAIN_BEACON_BLOCK, temporarily rename BeaconBlockHeader to BeaconBlockHeaderRLP to allow for gradual re-merging without disrupting RLP; mark a few unchanged functions and data types, implement get_temporary_block_header/get_empty_block/should_update_validator_registry/processBlockHeader/cacheState; update a few others

* a dozen or so more trivial mostly comment changes, finding more unchanged parts of 0.5.0

* several more trivial changes; goal is to reduce noise around the upcoming substantial changes (epoch processing, etc)

Zahary Karadjov 903cb8a8b5 A LibP2P-based networking stack;
To enable it, comment out the 'withLibp2p' line in nim.cfg

The history was squashed in order to remove an accidentally
commited binary file.

Other changes:

* SSZ was adapted to use the common serialization framework

* gossibsup.subscribe is not using async handlers at the moment
  and this allowed me to simplify it

Zahary Karadjov 8f9a5441f1 More reliable network simulation
You'll need the latest versions of nim-eth-p2p, nim-serialization
and nim-json-serialization.

Before starting the simulation script, make sure to delete any previous
json files from the simulation folder:

```
rm tests/simulation/*.json
tests/simulation/start.sh
```

This should survive the creation of few blocks before diying with a
block validation error.

* Message is a Blake2 hash not simple concat

* Address comments:

- Range change in parent_hashes computation
- Slot not beind module Cycles anymore
- justified_slot part of the hash

Not addressed: using parent.slot_number instead of block.slot_number
