Development mode controls CSS/JS minification

- When dev mode OFF (default): loads template.min.css,
  template.min.js, minified theme CSS, and minified FA7
- When dev mode ON: loads unminified sources for debugging
- Uncommented developmentmode field in templateDetails.xml
  with default set to 0 (off) for production use
- Updated language strings to describe minification behavior
- Resolved hero-card-max-width to 800px
