#208 SequenceGraph issues with unusual amino acids

[Brian Smith]

Opening a v2 project containing non-natural amino acids in v3.0.b2 and displaying the Sequence Graph generates the following traceback.

INFO : AnalysisAssign.showSequenceGraph : application.showSequenceGraph()
INFO : Gui.echoCommands : application.sequenceGraph.setNmrChainDisplay('NC:A')

v2 project for this. There's also an issue with the COSY spectrum name not transfering properly.
