Icon fonts loaded by script, and colour emoji on Windows

A classified ads site keeps its icons in a web font, declared in a stylesheet that its loader script adds after the page arrives. Floati applied that stylesheet's rules but never fetched its fonts on this path, so every icon fell back to an empty box. Now the fonts of a script-added stylesheet load the same way as the page's own.

Windows keeps its emoji as stacks of coloured shapes rather than pictures. Floati now reads those layers from the system's emoji font and paints them, so emoji on Windows are in colour instead of boxes. They use the flat colours the font provides; the reference browser on Windows also draws the font's gradients, which comes later.
