arrowtype/recursive v1.081

Make default numbers fully tabular, add fuller pnum feature, and other tiny fixes & upgrades

on GitHub

The main change here is that the default characters for all instances (Sans included) are now fully tabular, for better use in data tables, numerical animations, invoices, and more. They were always intended to be tabular by default, but they were unintentionally given kerning that made them not-quite-tabular. The kerning that was present was useful, so it was moved into a fuller proportional numbers (pnum) feature, and can still be activated for better text flow.

Overall changes:

• Adds a minus.superior glyph, for negative exponents
• Aixes the width of the prebuilt ½ glyph in Sans styles (Closes #479)
• Adds a ratio glyph (Closes #480)
• Adds mu (μ) as a greek character. It was already there under the mu.math Unicode value, but this will make it easier to find and use (Closes #481)
• Fixes not-quite-tabular figures (Closes #482)
