Remove commas from tags

[salcode]

As per https://jekyllrb.com/docs/posts/#tags "it will automatically split a string entry if it contains whitespace."

Commas are not treated as split characters. Because this file had commas in it, an additional tag, which was empty, was being rendered.

Resolves #11
