Default to Arial for names; give the Arial atlas full glyph coverage

Regenerate arial-atlas.{png,json} from a full Arimo TTF (latin + latin-ext) covering the same 32-383 range as overpass (319 glyphs, no Latin-Extended gaps), and make Arial the default name font (name.classicFont defaults true). Overpass stays for WorldTextPass, the structure-level MSDF option, and as the alternate name font.
