More Tools (Polymer)

• Updated for 1.21.2!
  • Mojang changed a bunch of stuff so this update is actually kinda big.
• Added support for useOnBlock for excavators and saws.
  • This means you can now use excavators to create 3x3 paths!
  • The same goes for saws.
• Added version check for client-side installations.
  • This means you will get a warning if your local version deviates from the server version, which could cause incorrect previews, models and/or translations.

Everything was tested and should work as expected, though if you find something please report it.
