Merge pull request #138 from ethereum/vbuterin-patch-3
Move specials into block processing, and clean up specification

simplify merkle tree chunking
* pack small items tightly to fit more items in single chunk, decreasing
the number of hash operations needed
* remove chunk padding - hash algorithm will pad to its own block size
anyway
* express data length in number of items instead of binary bytes at leaf
level (equivalent)

Move specials into block processing, and clean up specification
Moves the procedure for handling specials into the per-block processing loop. Cleans up the specification for handling them to be more unambiguous, and changes the formats to be more readable and simpler to implement.

* Add shard blocks, shard data roots and how data is computed into crosslinks

Includes:

* Shard block structure
* Shard block header verification rule
* Shard block fork choice rule
* Shard block body verification rule
* Crosslink verification rule

Possible simplification: require `calc_block_maxbytes` to always output an exact power of two; if we desire the average maxbytes to be smooth, we can simply make it a pseudorandom chose between powers. This reduces some of the padding complexity.

* create separate files for phases (#125)

* create separate files for phases

* fix links

* add shard block pre processing conditions

* cleanup

* remove 'essentially'

* Updated handling for beacon chain skipping slots.

* Handle missing slots more

* modify attestation validity rule for crosslink hash

Fixed bug in previous version
Validators cannot simply be "popped out" of the list because it's super-important for validator indices to be immutable.

Instead, the validator stays until a new run of `add_validator` swaps it out.
