From 681358adcfc8d1471ca53c3af246bf80a885ef98 Mon Sep 17 00:00:00 2001

Subject: Refactoring

- Edited log messages and types
- IPFS `cat` is now calling `get` which in turn searches for already
  gotten file, otherwise fetches it.
- ak-data-expand is now a function of _ak_zblock lib (_ak_data_expand)
- Removed ak-sm-hash-to-path as it lives in _ak_fs lib now
- Removed _ak_title_description and _ak_help from ak in favor of _ak_usage
- Tweaks around native FS over IPFS strategy

Note that we are preparing the ground for migration to AKFS as well
