Refactor "Published on, n comments." string
I think this is a better format for the comments string, so translators can change the word order if they need to do that.
Optimally, we'd use ngettext for fetching the plural for "comments", but I don't know if you have support for that.
- I don't have the website project set up right now, so this is completely untested.
- Run the translation update script after merging if you want to have this - I haven't done this merge in order to minimize merge conflicts.
