Added "Flow Rate", "Jewelry", and "Typography" sections to the conversions. Added "norm", "sci", "eng", "acc", "frac", "nCr", "nPr", and "tau" buttons to the layout editor. Added "tau" to the constants, and as a 2nd function of "pi" in most layouts. Improved the layout editor with all the commands and keyboard shortcuts from the macOS version. The "Clear on Open" option will now only trigger if you haven't used PCalc in the last five minutes. You can now use combinations and permutations in user functions and conversions. You can now edit buttons to display any SF Symbol as an image. Now show a preview image when picking an SF Symbol. Menus are more consistent with the macOS version.
