Requirejs optimizer is able to at least start running now.

Run it like

	cd client
	r.js -o build.json

(doesn't fully bulid yet, still trying to figure it all out)
Optimizer can now build main script file!

I have no idea how this code worked at all before this... Like even
on the regular client.
Make the worker use the same require root as the main page, this should
simplify our build process a bit (and make the path resolution seem less
magical).
The build works now! Just set BUILDBLAST_PROD="true" (or any other value other
than ""), and you'll run in "prod" mode, with minified scripts and css!
Remove superfulous log statement.
