Add Czech translations

[graciousgrey]

The scope of this issue is to add translations for a new language:

Acceptance Criteria:

Add frontend translations

• In /frontend run npm run gettext-extract
• Install a translation tool e.g. Poedit
• Open the /frontend/src/locales/translations.pot file with Poedit
• In Poedit click on "Create New Translation" at the bottom --> select the language, and start translating
• When done, save your translation as *.po file using the two-letter language locale as name
• Add the new language in /frontend/src/options/options.js
• Run npm run gettext-compile
• To test your translations you need to build the frontend again using npm run build or npm run watch

Add backend translations

• Run make generate
• Open the /assets/locales/messages.pot file with Poedit
• In Poedit click on "Create New Translation" at the bottom --> select the language, and start translating
• When done, create a new directory (using the locale as name) and save your translation there as default.po

Ok, now i noticed "fuzzy" flag causes that the translation won't apply those lines at all, dang it. 😄

And one thing i want to make sure, what "Checked" in the photo editor means? I thought it has something to do with Review but after an inspection in the GUI it doesn't look like so.
