A theme showcase blogdown site

[tcgriffith]

I have been thinking for a while about building a dedicated hugo/blogdown site to display various xaringan themes. Recently in issue #232 I've created a prototype of the theme showcase site, however this might be a bit off-topic so here I would like to open a new issue to discuss it.

Here is how the site looks like now:

In this site I aim to do the following:

• [x] Generate a thumbnail for each slide.html.
• [x] For each theme, create a blogdown post. In the post we can include instructions to use the theme and embed the slide into the post.
• [ ] Add author info so that proper credits were given to the theme authors.

I'm pretty happy with the look and feel of the showcase site now. Any Thoughts/suggestions :smiley_cat: ?
