New S2 editor technology possibility

[foxfirefey]

Was following Skywriter/Bespin/Ace, but it looks very clunky and more focused on a complete solution with a server backend then convenient embedding. Apparently CodeMirror is the most popular choice for embedding editors into other projects.

This post brought to you by attempting to translate layeredit.bml into Template Toolkit, and almost succeeding, though apparently need_res isn't something that works when you're not in a site themed page and I need to figure out a way around that.
