FEATURE: Improve Site Performance

[pioorg]

Hello
This is something in between a bug and a feature request.

In short, the theme doesn't perform super well when it comes to testing the mobile view on PageSpeed insights.
You can take a look here: https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fthemes.gohugo.io%2Ftheme%2Fhugo-future-imperfect-slim%2F
I've run several tests of this page and usually the score is seventy-something, which isn't great, but it's not terrible. I've never reached the green bar.
I know there are different opinions on "is this report trustworthy or not", but in general I guess being green would not harm.

Cheers
Piotr

It would be nice to remove jquery and related plugins and optionally load the galleries (I don't use any of the extra features). Then use the new script bundling features in 0.74 so we are only loading one file instead of many.

I have toyed with getting rid of jQuery as we look at #165. While not impossible, there is a lot of refactoring that would need to be done (which I'm not opposed to. I have just refactored the entire theme twice already, so I need a little break from big projects - 😆).

I would love assistance with PageSpeed improvements from people more versed in optimization. I marked this as in progress, but my progress is minimal.

EDIT: Relevant tool for anyone that is interested in refactoring the JS. Also, I'm sure there are some optimizations that could happen within the code itself as well.

See Also #230. #245 is a step towards this. Still waiting on #165.
