shachain: grammer fixes, gofmt conformance, slight interface changes

Browse Source 
This commit contains a series of post-merge fixes which include:
  * ToBytes -> Encode
    * As the former version doesn’t _require_ allocation of new slices *
  * Store -> AddNextEntry
    * To communicate to the caller that entries MUST be added
      in order
  * Several grammar, spacing, spelling and gofmt fixes.
