Remove references and copyright 
Licensing is done at the repo level. The listed references are awkwardly incomplete (only the Python implementation was listed when we have ~10 implementations, and only the Casper paper was listed where we could add many ethresear.ch posts).

Move the ordering of the definition of process_deposit. 
This move matches the symmetry of the other operation processing definitions.

f5c5c166af Replace custody challenge game with JABS (#812) 
See also #818.

===

* Replace custody challenge game with JABS

Replace the existing proof of custody game with a new game ("Justin's Awesome Bit Sum" or JABS) that works as follows:

* The data `D` is split up into 512-byte chunks `D[0] .... D[n-1]`, and use a mix function `mix(subkey, data) -> {0,1}` (currently the first bit of the hash of `subkey+data`). We calculate `M[i] = (mix(D[0]) + ... + mix(D[i-1])) % 2`, and set the custody bit to `M[n-1]`
* Anyone can challenge by providing the full `M` where `M[n-1]` is not equal to the custody bit
* Anyone can respond to a challenge by providing a specific position in `M` along with a branch of the data where `M[i-1] ^ mix(D[i]) != M[i]`

The maximum size of data is now `2**6` epochs *  `2**6` blocks * `2**14` bytes = `2**26` bytes, so assuming 512-byte mix chunks the maximum mix size is `2**17` bits or `2**14` bytes. The average mix size is `2**8` bytes.

Separate document for phase 1 custody game (#818) 
The 1-round custody game has been implemented. Many bugs squashed, and a bunch of polishing done. Miscellaneous known issues (~8 of them) to be resolved in separate, smaller, PRs.
