* Use DynamicHasher256 to support Blake2 or Keccack depending on chain * remove Config::Hash associated type, replace with HashFor<Config> alias * Fix doc links * fix wasm tests * Don't strip system pallet associated types. check System.Hashing, not Hash. Rename BlockHash trait to Hash * Tweak comment * fmt * fix merge * Fix typo
