Re-compile and minify

My last pull request didn't update the concatenated and compiled versions! Sorry about that.

I've concatenated the files as before for tv4.js. I used [Uglify JS][] for minification, so feel free to ignore this bit if you have a different preferred minification tool.

I was thinking maybe using a task runner/build tool like [Grunt JS][] would help?

Cheers,
