Cleanup, package.json, and some changes.

Moved files around a little. HTML that's served up is now in html/.
Moved speed.js to bin/.
Moved javascript in speed.html to html/speed.js
Moved configs out from speed.js to bin/config.json.
Changed up uploads so that the tests are 1/6 of the last download size
 or maxUploadSize, whichever is lesser.
Finished (?) package.json. Might be added to NPM soon!
