Change jQuery version from 2.0 to 1.10.2

The official H5BP team is staying with jQuery 1.X for now as 2.X doesn't supports IE<9. I'm not questioning if IE<9 should be removed or not, but it's simply honest to stick with H5BP recommendations if this generator-jekyllrb template is called "H5BP".
Switch to jQuery 1.10.2 on bower.json file.
