removed jquery to close #34, bootstrap is a little harder though

since we're not using standard bootstrap, but a theme from bootswatch.com (yeti), I'm not sure if this can be installed via bower and might just have to stay under our version control... unfortunately.

and everybody is going to have to run `bower install` inside the repo once to get a local copy of jquery. use `npm install bower -g` if you don't have bower installed.
