intltool automatically embeds comments in the po template
if they are directly before a translatable string. From
now on we will try to avoid leaving accidental comments
and instead put descriptive comments for translators
before strings, starting with 'i18n'.
Based on the implementation of localization via Gettext
contributed by Enrico Tröger, a few adjustments were made
to allow Midori to be properly localized. Initially
German is fully supported.
