Publication info popup dialog (metadata), punctuation and separators should be localized

[danielweck]

For example, in French, colon separator is between space characters (before and after), whereas currently there is a space only after (which is fine for English locale).

identifier has been hided

Re-opening the issue (this isn't about hiding the UUID).

See screenshots in English and French that pin-point where the missing spaces are (English OK, French
lacks separator spaces):

[panaC]

very annoying this issue because it's necessary to change all locale file. Colon seperator is hardcoded !

Yes, the translated labels should all have interpolations for real localisation / globalisation, accounting not only for token positioning but also date format, etc.
