shorty: Some trivial formal replacements of quoting characters.
Added a repository wide l10n folder to hold the localization resources.
Contained are a short README and a subfolder 'templates' with two
gettext 'pot' style l10n template files, one for each app in this repo.
Note that those template files are to be maintained manually, they are
not automatically updated or extracted as in other repositories. This
is  due to the fact that the apps in this repo implement more complex
mechanisms where the automatic extraction of tokens simply fails miserably.
