* If there is only one protein_coding transcript in a gene, use it as
  the canonical transcript but make sure it doesn't have internal stops.

* If a seq_region_name is given, zero set the canonical_transcript_id
  and canonical_annotation, otherwise zero set all
  canonical_transcript_ids.

Added minimal doc.

processed_transcript', if gene biotype is protein_coding.

The TranslationAdaptor now has a fetch_all_by_Transcript() method with
which it's possible to get all translations for a transcript.

The fetch_by_Transcript() method now uses the new
canonical_translation_id field in the transcript table to get the
canonical transcript.

For species without alternative initiation (all Core speaces today), the
semantics and the results are the same as before.

Using the API from now on, without patch_56_57_e.sql applied, will
result in SQL errors.

The TranscriptAdaptor now knows how to store the canonical translation ID.
