A couple of script changes after CI integration

Browse Source 
- Renamed struct_.py -> structs.py again.

- Removed lfs.csv, instead prefering script specific csv files.

- Added *-diff make rules for quick comparison against a previous
  result, results are now implicitly written on each run.

  For example, `make code` creates lfs.code.csv and prints the summary, which
  can be followed by `make code-diff` to compare changes against the saved
  lfs.code.csv without overwriting.

- Added nargs=? support for -s and -S, now uses a per-result _sort
  attribute to decide sort if fields are unspecified.
