#361 Diffs in seqs displayed: exon or transcript

[Brian O.]

Not sure if this is a bug or a feature but the sequence that is shown when a single exon is selected and show sequence is chosen does not always reflect the sequence that is shown when the entire transcript is selected. An example, if you look at a case of 'stop_codon_readthrough' e.g. CG11177 then looking at sequence when the exon that is read through is selected shows a '*' in the place of the read through codon but if the entire transcript is selected then 'U' appears in sequence. Same applies to translational frame shift cases, and if a non consensus start codon is set.

[The issue is that if you only have an exon, you don't have the special peptide for the transcript--you translate the single exon on the fly, so SeqFeature.translate is called. But since Transcript.translate calls SeqFeature.translate and doesn't seem to do anything special with the result, I'm not sure why it comes out differently.]
