(1) Use phony %.min.js files (2) copyright headers in d3.*.js (3) Makefile!

----

Due to our support of free software, we have two (uncommon) requirements
for .min.js files:
 1. They preserve the header comments; for license-identification
 2. They can be created with free software; a free minifier, SaaS does not
    count.

The only viable way to do this is to use django's compress.py, which
requires the Google Closure Compiler, (or use the closure-compiler
directly), which is not (yet) packaged for Parabola.

So, for now just copy the *.js to *.min.js in order to avoid having to
change URLs to temporarily point to the non-minified versions until we can
properly minify them.

----

Add copyright headers to d3.js files, which by default ship without the
copyright included in the file, despite being free software.

----

Create a Makefile that automatically does this. It fetches the d3 and
jquery .js files, adds the copyright headers to the d3.*.js files, and then
copies .js files to .min.js files.
