843976865e ifdBuilder.dumpToStrings: Fixed usage of II. 
- We were ambiguously treating it as both the parent II in some places
  and the child II in others. It's supposed to be the parent II.

3cee9b956b ifd_builder_encoder: Fixed subtle but detrimental bugs. 
- ifd_builder_encode
  - Bugfix: We were assigning the "next" IFD in correctly (so, chaining
    was broken).
  - Bugfix: We weren't using the right value when *writing* the "next"
    IFD offset (so, chaining was, again, broken).
    - The same IFD was showing as both a child and a sibling, so we were
      seeing the EXIF IFD also being chained-to by the first root IFD
      instead of the *actual* sibling, but only after encoding and then
      decoding (so, this had to be tracked down in the encoding
      semantics, which was non-trivial).

  - Added a test for the stuff that we fixed.
  - Implemented journaling, where we can dump a hierarchically-formatted
    list of operations involved in a completed encode.

- ifd_enumerate: Added (Ifd).TagValueBytes() to return the raw tag-
  value's bytes (rather than just having (Ifd).TagValue(), which returns
  the value marshaled into a string). Good for comparing raw encoded
  and decoded values without imposing interpretation (which gets us into
  trouble with unknown-type tags whose values are non-standard and
  undocumentedand, therefore, not actually parseable).

- Rewired a lot of print and dump functions.
  - For naming-specificity as well as functionality.

- Removed from debugging.
