Using bootstrap-map-js code, added grunt/jshint, moved code under src, renamed repo

* Using code from bootstrap-map-js so index.html is now responsive
* Added grunt w/ livereload, jshint, etc to assist in development
* Moved source code under `src` so we can add folders for tests and builds
* Renamed repo to `dojo-bootstrap-map-js` which is more succinct and inline w/ the [bootstrap-map-js](//github.com/Esri/bootstrap-map-js/) repo
* Updated README and package.json accordingly
* Removed more unused files from v2 and misc clean up
