The idea is to create a new packaging system for add-ons that makes it much easier to get started with add-on development. There are 3 parts to this idea:
* Merge install.rdf and chrome.manifest into a single manifest file in JSON format.
* Change the way chrome URLs map to actual files, in order to allow a more flexible add-on structure.
* (optional?) Optimize the installation process for performance.
The old system would need to continue to work with the new one.
