String “ days ago” needs a variable placeholder

[fitojb]

Otherwise, it’s impossible to translate it idiomatically in several Romance languages; for example:

%d days ago Hace %d días

instead of the current

days ago días atrás

In general, please don’t split strings that belong to one message. See http://daleslocblog.blogspot.com/2011/10/concatenation-is-evil.html and https://rimas.kudelis.lt/2010/06/14/software-that-is-actually-localizable/

@fitojb Many thanks for raising this issue. Good article and emphases the issue with sting concatenation. Will go through the list of translatable strings and modify as far as possible to make translations accurate.
