Changes made for this site (original: https://github.com/leereilly/Coil @ ea6fd3afae10a6d8a53b07e82be4211619206ede,
a copy of Hakim El Hattab's Coil; the commit is authored by Hakim El Hattab)

- Copied only runtime files: index.html, css/, images/, js/coil.js, js/util.js, js/libs/jquery-1.6.2.min.js
  (jQuery keeps its own license header), plus LICENSE unchanged. Not copied: README.md, favicon.ico, js/header.js.
- index.html: removed the Google Fonts links (Molengo, Ubuntu); text falls back to system fonts.
- index.html: removed the expandable page header (About text, Facebook like iframe, Twitter widget script,
  Flattr button) and the Flattr loader script. The author credit is kept as a line in the game menu:
  "Coil by Hakim El Hattab - Copyright (C) 2011 - MIT licensed". js/header.js (which only toggled that header) is no longer loaded.
- index.html: viewport meta changed from "width = 450" to "width=device-width, initial-scale=1".
- js/coil.js: the 900x510 game area is now scaled with a CSS transform to fit its frame, and mouse/touch
  positions are mapped back through that scale. Previously the game was a fixed size (or the full window on
  phones and tablets) and was cut off in smaller frames. The world is now always 900x510.
- css/main.css: added styles for the menu credit line and the transform origin of #game.
Game rules, scoring and graphics are unchanged.
