Integrate resources (JS, HTML) into server

Hey Chris,

I like Ji a lot because I think it's a good a way to build an accessible GUI framework for Haskell, something which we currently lack. Not sure if Ji is a good way to write remote web applications, but that's a separate issue.

To make Ji ready for distribution with .cabal, I have integrated the JS and HTML resources into server source code by means of QuasiQuotes. This provides a canonical way to distribute that pesky `x.js` driver code, which I have renamed to `ji.js`.

The patch is not complete yet, I haven't ported the example code yet.
