[Lazarus] Translations / Localizations for controls at design time

AutoTranslate based on user Loacle is a disastrous idea, especially if the
program is multi-lingual.  Eventually what should be LangA - LangB will end
up on a system where it is LangA - LangA and make no sense at all.
AutoTranslate also fails badly on such things as LongMonthNames[N] if the
Locale is RightToLeft.  It returns '???'.  The workaround is easy, but I
spend too much time writing workarounds.  And unless you test with both
LeftToRight Locale and a RightToLeft Locale, you are likely to assume that
AutoTranslate will take care of you.  You will likely be wrong.
