Implement prototype of psos integration

[lukasjelonek]

This code adds psos support to the asap annotation details table. It is implemented in javascript only and adds biojs-io-fasta and psos.js as externally loaded resources (from remote servers). Visually an "Analyze with Psos"-button is added to each row in the table.

The code was tested manually as a code snippet in the browser web console on random annotation details page from the example pages. For use in local results it may be necessary to include the fasta as a string in the data.js file and to adapt the loading of the fasta sequence data.
