downloads: refactor ordering

There are no way to predict the order in which lua will iterate over a
hashtable so we use an array instead.

We also set a fixed number of colors which we pick insstead of hardcode
the flavor name in the CSS. This is so we can change name of the flavors
without needing to modify the CSS.
