Upgrade jquery to 1.10.2, upgrade knockout step-by-step to 3.0.0 with new minor version for each step

Based on https://github.com/bramstein/knockout.selection/pull/75 and https://github.com/bramstein/knockout.selection/pull/76 (specifically this comment: https://github.com/bramstein/knockout.selection/pull/76#issuecomment-27800268 ), I've made this new combined pull request. 

This pull request upgrades knockout in 3 steps from 2.1.0 to 3.0.0, so if needed, one can easily branch off from a specific tagged release.

@bramstein It might be nice to also npm publish the three versions I tagged (which I'm not able to do), could you perhaps do that?
