Add more cotent to publicArtifactType and projectType to model research/academic careers

[mikel-egana-aranguren]

Some of us have worked both in academia/research and industry, but the current CV schema lacks some elements to represent it. At least:

• publicArtifactType should include journal papers and conference proceedings.
• projectType should include funded research projects (Those could be added as other but I think they are at least as important as side projects, as some can have enormous budgets).

Thanks, keep the good work!
