Enhance Callback constructor for easier use elsewhere
Refactor utility functions to save a little space
WARNING comment only
Add Meeko.Async as namespace.
Meeko.async becomes Meeko.Async.wrap (still available internally as async).
`isAsync` becomes `isCallback`.
Move `<link title="nodecor">`, `<style title="nodecor">` stripping from
`page_prepare()` in `HTMLDecor.js` to
`panner.options.normalize()` in `config.js`.
Remove window.onunload handler.
It disables bfcache + can't remember how I justified it
Forgot to include index.html two commits ago.
Tweak boot-script detection
Allow `config_script` to accept an array of scriptURL or function() {}
toArray() was breaking on HTMLCollection in IE6
script.onreadystatechange fires `complete`  too early on IE10.
Use script.onload wherever it is detected
