Bug 568691 part C - Register all components based on reading .manifest files from the components directories. Binary components auto-register using "binary-component name.dll". JS components register using "component CID file.js" "contract @mozilla.org/contract;1 CID" and "category categoryname keyname value".
This patch has some bugs, specifically we stop looking for .manifest files in chrome/. I will fix that in a followup. It also probably breaks non-libxul builds because of ordering issues.
Another followup will actually fix our in-tree JS components and add build machinery for creating a proper components.manifest file.
