Add Google Scholar as social handler in 'Personal' plugin

[schmittner]

Along the lines of #29, it would be nice to be able to add a Google Scholar author identity, which many researchers have. Since you already offer ORCID, I assume that this would be interesting as well.

According to Wikidata:

• Base URL is https://scholar.google.com/citations?user=AUTHOR_ID
• Regex for the AUTHOR_ID is [-_0-9A-Za-z]{12}

Thanks for your great work.
