* get_proposer -> get_beacon_proposer, block -> slot
* Move proposer sig to the end of a block
* Update specs/core/0_beacon-chain.md

* sig -> signature
* add type hints for get_beacon_proposer
* 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)
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.
* Added tree hashing algorithm
* Update simple-serialize.md
* add one more ref to tree_hash
* Add the zero-item special case
* list_to_glob to handle empty list
* 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
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.
* refactor hash in simple serialize to support arbitrary byte length
* make comment clearer
* add deserialization of hashN
* formatting
* remove specific hash examples
