Change a few things in settings:
    - Added myself as admin.
    - Add ALLOWED_HOSTS which is required in production.
    - Modified the logging config so that Django doesn't send error emails in DEBUG mode.
    - Fixed indentation

hife the translation message
Move the logic of meta description to a template tag.
- Create a meta description template tag that generates the description string.
- Use best-practices for translation. Instead of splitting the string into smaller pieces and concatenating them, we should make only one string that takes variables.
- Included new translations for the "ar" locale.
Updated translations for other languages.
