Tightening checks in Vega for Selenoproteins.
First stage commit only. Partial functionality (detailed below), but works and reduces chance of missing problems. 1. Made exception data structure richer for check_for_stops to allow a number of different types of exception to to be expressed. 2. Added a new exception type, that of known TGA-stopping Sec-coding transcript. 3. Added data-structure to add_selcys stop checking to allow specification of known TGA-stopping Sec-coding transcripts.
