Russian translation: (vercel#172)

* Russian transaltion:
- Added russian localization
- Added translation for Features from index page (components/features.js) with fallback to English
- Small typo fixes found during translation

* Added SVGs translation option (#2)

- Contributers now can easily translate SVGs by just passing path string
- Moved all hard-coded SVGs from pages to components/diagrams/
- If no 'translation' is provided it fallbacks to default locale (en-US)
