Placeholder stuff in builder script.

Commented out the code that will in the future be used to increment the
version number using NPM's native "version" command. This will update
package.json and hopefully callback with the new semver string which we can
use the same way as before when creating the new directories and replacing
the magic strings in various files. Manually set the version in package.json
to 0.1.24 which is the current version on literal-trees.co.
Height given by height not th.

E.g., GET /?height=2&depth=3
Grunt integration.

$ grunt requirejs works.

- Put the main app logic (which simply calls require['app/tree']) into
  main.js.
- Moved the RequireJS configuration stuff from js/main.js (formerly named
  js/app.js) into it's own file: js/require-config.js.
- Left comments in source.html describing how to switch back and forth
  between the file built by "grunt requirejs" and those existing in the
  normal source tree.
