Basic restructure to start perf testing
Move scripts to end of <body>
Modify audio file loading

* Use (smaller) ogg files rather than wav files
* Don't load audio in HTML, only in JS
* Don't load two audio files for each sound: just manage start/stop
  better.
HTML file cleanup

* Use correct DOCTYPE
* Reduce length of meta tags where possible (e.g. charset)
* Use querySelector() so we can remove the ID attribute for
  the viewport meta tag
* Clean comments out at build time
Replace background pngs with jpgs
Include README.txt with distribution
Load HTML in pieces

Only load the HTML needed for the front page to begin with;
then load remaining HTML and initialise everything when it's done.
Use localStorage sparingly
Defer audio loading until needed
Use delegate to reduce number of event handlers
Load JS after DOM has loaded
Switch to jq.mobi

A smaller library, with practically the same API as jQuery; also
supposed to run slightly faster than jQuery.
Correct the app name in package.json
