i18n::problem_text shows a problem as the field's label and the issue
in the current language ("Titel: braucht einen Suchbegriff (oder „ist
leer“)"); problem_line puts the rule's position first ("#2 Title: …")
for the sidebar's tooltip. The editor's row notes and the sidebar use
them.
All 20 issue texts are translated in the seven locales, each quoting
its own operator names ("ist leer", «пусто», 「が空」), with あり / なし
for Japanese yes/no. A test requires every issue to be translated in
every language and checks English and German output.
Also corrects the zh-hant sidebar tooltip to name the menu as it is
(編輯智慧型相簿…).
