Add a more detailed error message when the app bundle can't be imported.

Fixes issue #47.

Also:

- Fix the wild table sorting.  It was broken after removing the columns
  about timing.
- Add web code to the line count.  csv2html.py is new for the OSH 0.2
  release.
- Fix a build issue with osh-quick-ref.  This build step outputs both
  code that goes in the app bundle and docs that go in _release/VERSION.
