Initial project setup

.gitignore to keep pesky generated stuff out of version control
Cakefile to manage build tasks
main.js as a starting point for browserify -> zombie.js
package.json to describe the survive project
survive.coffee, the main entry point for the game
rot.js, a rogue toolkit library; plus a minor addition to integrate with module system
style.css, bare bones stylesheet for the game's html page
survive.html, the game's page

Note that the code checks for window.msRequestAnimationFrame.
Those running Microsoft Internet Explorer can't play the game at all.
