Add hyperlinks from specs to online examples

Such as L1V3_repressilator.omex: https://github.com/SED-ML/sed-ml.github.io/raw/master/examples/L1V3/L1V3_repressilator.omex

Done! I put in links to the SED-ML files directly, but the links are really large. Can we add just the SED-ML itself (as opposed to the version that's hidden inside an OMEX file) to sed-ml.org?

We could unpack those example archives and add links to the individual files.
