2.0 UX Changes (#295)

Partially addresses #237
- Unhides the load button on smaller screen sizes
  - There's no way to actually load new web archives when this is hidden
- Minor text updates
  - Renames MIME Type to Media Type
  - Punctuation fixes
- Reorder main application controls (#237)
  - Group navigation related controls together on the left side
  - Move full screen to the right side
  - Enable navigation controls on mobile
- Renames URLs tab to Resources - now that we have more space (because we moved the archived item info
to a dialog), we can make these titles visible when space is available to do so!
  - This is now in-line with the docs (both current and new!)
