Rethink download link area

[Apreche]

The original design for the download link area was fancy and worked well, but the reality is that we don't have the functionality to support that design. There's only one download link, so the menu is gone. And we don't have the shownotes functionality to support the left link. With the left link gone, the symmertry is lost as well.

It's also strange how the download MP3 link starts gold and hovers black. Meanwhile the see forum discussion button starts black and hovers gold.

Let's replace this section with a grid of buttons that are all identical in design. They can all be black and hover to gold, so there is consistency. On desktop they can be the size of the Download MP3 one, and arrange into a nice row, wrapping to a grid if necessary.

On mobile they can be full width, nice and easy to scroll through and tap on just one.

Then if we get functionality for shownotes, other download options, etc. it will be very easy to just add more buttons. No menus or anything.

This design will also help to get rid of non-obvious menus like this. Of course this is a data error. There shouldn't be two forum links on this book club. However, it is legal for there to be multiple related links of various types on the same content. And in that case, we should give each one its own separate button, and not use menus like this.
