Untranslatable strings in s-c 5.1.8

[Gabor Kelemen]

I have found some i18n problems:
- untranslated strings in softwarecenter/ui/gtk3/review_gui_helper.py
- one string with misplaced parentheses in the same file: err_str = _("%s\n%s" % (err_str, err))
- Files are missing from POTFILES.in

Attached branch should fix these. I'm not sure how the string surgery done to the "There was a problem posting this review to %s" string will play in all the languages (think RTL), but I marked it for translation to be sure. We will see if there will be any complaining :).
