1.635 Update - updated crafting costs and a couple new features

- Adjusted many item costs and workbench tiers needed to match the Rust update using the Rustafied doc. Please let me know if anything is wrong.
- Added way to include an external folder to the file panel. This is very helpful for those using copy-paste, allowing direct access to the oxide folder. Just paste the folder path in the input field and click the button shown below. Not sure if there will be issues with macOS or linux so any feedback would be great.

- Added "cull distant parts" option in options, allows for building huge designs without slideshow FPS. Planning on adding a way to set the distance eventually. Be careful with edit mode, culled parts can still be selected.
- Fixed red button prefab path being wrong with copy-paste exports.
- Counter target value are now included in copy-paste saves now, the plugin still needs the related line of code to be uncommented.
- Fixed invert-Y mouse option not working.
