Removed `--normalize` option and normalization functions from Shared.

* Removed normalize, normalizeInlines, normalizeBlocks
  from Text.Pandoc.Shared.  These shouldn't now be necessary,
  since normalization is handled automatically by the Builder
  monoid instance.

* Remove `--normalize` command-line option.

* Don't use normalize in tests.

* A few revisions to readers so they work well without normalize.
