Publish to bower

I am preparing the bower.json file to be published to bower to fix #37, but I've realised that the license PR #16  never was merged. 

I've specified dual-licensing MIT/APLv2, but I would like to double check this with you @jamesarosen. Also merge the license PR would be nice.
I gather this changed with the major version bump in jQuery. We should probably make multiple builds -- one for jQuery 1.x and one for 2.x.
