[packaging-on-the-web] Consider manifest~like approach instead of SPF (#23)

We didn't come to any resolutions on the public-web-perf list, so just want to raise this here such that the feedback and discussion doesn't get lost. The highlights:

- https://lists.w3.org/Archives/Public/public-web-perf/2015Jan/0027.html 
- https://lists.w3.org/Archives/Public/public-web-perf/2015Jan/0038.html
- https://lists.w3.org/Archives/Public/public-web-perf/2015Jan/0041.html

The entire thread is worth reading for full context, but in a nutshell the proposal is to revisit the use cases in light of omitting the whole "streaming package format" in favor of a ~manifest-like approach. I believe we can meet the required use cases without SPF, while also avoiding any perf complications introduced by SPF.
