Ideas for Arc XP

Both pb:external-resource and pb:page-resource should have an inline equivalent:

- minimize http requests and get critical "above the fold" CSS in front of the user as quickly as possible so as to increase time to render (a la Guardian)

- maintain critical inline JS in /resources/scripts (rather than a .jsp) and then reference in a .jsp

- maybe configurable via an "inlineResources" and "inlinePageResources" entry in an output-type file
