This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Adds infrastructure for react server rendering, and makes our 404 page use it. (Gotta start somewhere!) If a catalyst action has a NewTemplate attribute, it'll take whatever action was requested, e.g. root/main/404, and tell server.js to render root/main/404.js instead. The macros uri_for and uri_for_action are supported in React templates via regexp magic. The formatUserDate module has been moved to root/utility, since it uses server-only data.
