WIP: Icons set

[fiskus]

Please, confirm that you are not against this idea, then I can finish the rest migration of the icons.

Description

• Use "@material-ui/icons" instead of fonts fetched from CDN
• Able to use outlined icons
• Use correct and consistent icons for icons in file listing
• WIP: Only expose those icons that we use
• Rename icons: make naming based on the domain meaning instead of abstract MUI

TODO

• Unit tests
• Automated tests (e.g. Preflight)
• Confirm that this change meets security best practices and does not violate the security model
• Documentation
  • Python: Run build.py for new docstrings
  • JavaScript: basic explanation and screenshot of new features
  • Markdown somewhere in docs/**/*.md that explains the feature to end users (said .md files should be linked from SUMMARY.md so they appear on https://docs.quiltdata.com)
  • Markdown docs for developers
• Changelog entry (skip if change is not significant to end users, e.g. docs only)
