Remove Bootstrap css&js dependencies

1. Not all projects use Bootstrap. Get rid of that dependency and write minimal css and javascript needed to render the front-end.
2. Add a way to check for a pre-existing version of jquery in a page. If it exists in someone's project already, don't bother fetching and loading it again. Otherwise, fetch it from a CDN.
3. Clean up the front-end and make it presentable, you slob.
