Title: Removed call to put header into minified build, because it's already there.

Maybe uglifyjs has changed its behavior regarding comments at the beginning of a file, but it seems like space is of the essence in a minified file, so you may as well not have an extra set of copywrite/license information. Simple enough to do yourself in the Makefile, if you don't want to do it through git.
