jQuery should be updated

[stof]

Currently, you depend on jQuery 1.8.x. Node support in jQuery was not official in 1.x and 1.8.x relies on https://github.com/UncoolAJ86/node-jquery. This unmaintained project uses dependencies which are not compatible with node 4+

Hey, thanks for the report, and sorry for the delay getting back to you. With the availability of ember-cli I'm no longer actively using this module, and so haven't been maintaining it. Are you using it currently? Any chance you're interested in helping maintain?

I'm not using it. I'm a maintainer of Assetic, which has support for this tool (contributed by the community), and I saw this issue while working on running our full testsuite locally (where I have node 4 while Travis still has 0.10 on their PHP image). I was not aware that the tool was unmaintained (I see you added a note about it in the readme now)
