Add 7-day moving averages to download graph. Plus UI tweaks.

[hellp]

The non-stacked scattered chart as a basis reflects the download numbers
correctly. The stacked area chart before was a bit midleading. Both
approaches are a bit "noisy", so I added a 7-day moving average line for
each version number. This gives a higher-level overview and also makes it
easy to see when new versions overtake older ones in usage.

The colors were chosen to be colorblindness-friendly as well as having
a hot-cold metaphor.

Example, the futures crate, before and after:

Thanks, this looks awesome!! 🎁

Since you sent in this PR, we've upgraded ember, which seems to have gotten rid of window._, so I pushed a commit to your branch importing lodash, which worked for me locally. I also merged in upstream and I'm going to wait to make sure CI is ok before I merge this in :)

welp that didn't work, investigating....

I think this is hitting ember-cli/ember-cli-qunit#162 now...

[hellp]

I haven't looked into the newly appeared issue, but if it's only about the lodash usage, I think I can rewrite this without using lodash. It was just convenient to have it.

Turns out it was my fault :) I just rebased and force pushed to pick up this change: #562

I think lodash is convenient too, seems fine. Let's see if this goes green.

Yaaay, tests are green!!! 🍏 📗 💚 🥗 Tested it out locally and it's looking awesome! Thank you for your patience!!

Just my two cents: I saw the new graphs and I thought something was broken. Now reading this I like the moving average idea, but I think it needs to be indicated in the legend somehow.

I would even suggest removing the noisy dots. Or have a toggle to switch between averaged and raw data.

Loving the color selection and the use of a rolling average. Agreed with @durka that the dots initially made me think that something was broken, and I'd second a PR to remove them from the main graph (though I think it's useful to retain the raw data in the hover).

@bstrie could you make your comment on #567 too please? thanks!
