Hot-patch text-scale-mode with multi-face support

---

text-scale+ hot-patches text-scale-mode with support for adjusting the font size of multiple faces at once.

The vanilla Emacs' text-scale-mode only adjusts the default face. So when you use text-scale-mode in a buffer that happens to contain some text fragments displayed with non-default face (e.g. variable-pitch), you'll notice that their font size won't change. Things become ugly if you happen to use eww (the Emacs' built-in web browser) with proportional fonts rendering enabled (the default) — the entire EWW buffer just won't scale at all.

text-scale+ solves the aforementioned issue of the current text-scale-mode implementation by hot-patching. Hot-patching in this case means that after you have loaded this package, text-scale-mode will be "fixed" completely transparently to you. All your keybindings and custom settings (e.g. text-scale-mode-step) will work the same as before.
