update setup.sh, bower.json

add "resolution" property  in "bower.json"

- this is to escape dependency version conflict with "jquery".

- jquery which is installed into "bower_components" is "1.7" though this jquery isnt used in "style-guide"

- "style-guide" uses "jquery-1.9.0.js" which is downloaded from code.jquery.com

change "bower install" related command in "setup.sh"

- to simplify install process
