- introduce monero oct 2018 fork as currency `monero`
- remove monero7
- change all dev pools
  - those miner monero7 to handle the fork to monero
  - if the dev pool can not handle the fork to monero the currency is fixed set to `monero` (we can only handle 2 different currencies for user and dev pool)
- remove guards those prevent to use the currency `monero`

- reintroduce monero7 until the POW is final
- update docs (add cryptonigh_v8)

- rmeove currency `monero7`
- introduce `cryptonight_v8` and `monero8`

- add cryptonight_heavy derivate cryptonight_bittube2
- add coin bittube
- remove coin ipbc because this coin is now called bittube

- remove all cryptonight coins (algorithm cryptonight can still be used)
- update README.md

- add ryo currency
- update documentation

- update pools.txt
- add new algorithm `cryptonight_haven`
- update all backends

- rename cryptonight_fast to cryptonight_masari
- set dev pool to cryptonight_monero

solve #1494

- add algorithm `cryptonight_v7_stellite` (internal named: `cryptonight_stellite`)

- add algorithm `cryptonight_lite_v7_xor`
- update documentation

- fix dev pool algorithms
- add note to `pools.tpl`
- remove pool suggestion

remove fork version for sumokoin and monero7

- allow the dev pool to fork on a different block version than the user descriped coin

All algorithm are centered around the user coin description.
It is allowed to have two two different coin algorithms in the user coin description.
It is only allowed to use algorithms for the dev pool coin description those are used in the user coin description.
There are two ways to define a non forking coin.
  - set both user coin algorithm descriptions to the same algorithm and set version to zero
  - set the first algorithm in the user coin description to something you like to use in the dev pool
    and set the second algorithm to the correct representation of the coin. Set the version to 255.
    This will allow that the dev pool can mine on a different coin algorithm than the not forking user coin.
    Do not use an algorithm with different scratchpad size for the dev pool.

- expose cryptonight_lite_v7, cryptonight_heavy and cryptonight_v7
- remove cryptonight_lite

Graft is forking soon, with updated software released yesterday, to what
will be v8 in Graft (current Graft cryptonight algorithm is graft v7).
This commit updates the `graft` algorithm to recognize the fork and
switch algorithms.

Fork annoucement:
https://www.graft.network/2018/04/12/patch-1-1-1-released-major-network-update-block-65110/

-rename `mining_fork_height` to `*_version`

- add `fork_height` to currency
- refactor algorithm selection

- add new pow for AEON
- fix missing cryptonight-heavy selection for multi hashes

fix #1202

Fix CLI option start + make cli option pool into an added pool with top priority ithinstead of overwrite

This change fix #177 and compiler warning too.
