Idea: do not bake dygraphs into the tests

[mirabilos]

What needs to be changed to make tests.js not contain dygraphs itself? (Other than adding the extra <script…></script> tag to also load dygraphs.js to the two HTML files.)

This separation would allow nice things, like running the tests against the minified version as well.

This was hard (working around internal design, uhm, decisions in browserify and other tools), but I got it. We now run the tests against the .min.js as well, which I consider a benefit.
