change in i18n documentation to emphasise that unless verbose_name and verbose_name_plural are marked for translation, they will not be translated.

[kenneth gonsalves <lawgon@…>]

The current sentence regarding verbose_name is:

"It’s a good idea to add translations for the field names and table names, too. This means writing explicit verbose_name and verbose_name_plural options in the Meta class, though:"

This could be changed like this:

"Field names and table names must be marked for translation otherwise they will not be translated in the admin interface. This means writing explicit verbose_name and verbose_name_plural options in the Meta class, though:"
