#228 HTMX attributes prototype

[JPonte]

I was intrigued by this issue #228 and decided to see what the fuss is all about with this htmx.

I found it quite interesting to use Tyrian exclusively in the server and ship only the htmx.js to provide client side logic so I created a sandbox with JVM only that does that.
I'm no expert in htmx and there are way more features that I'd like to explore in the future, for now this is really barebones.

One thing I'm not happy with is the Trigger part for the hx-trigger.

Trigger(tyrian.htmx.Event.Input)
  .withModifiers(Modifier.Changed, Modifier.Delay("300ms")),
Trigger(tyrian.htmx.Event.KeyDown)
  .withFilter("key=='Enter'")
  .withModifiers(Modifier.From("body"))

gets correctly "compiled" to input changed delay:1500ms, keydown[key=='Enter'] from:body but feels a bit too verbose.

I'm not sure if this is of any use and if it's what you had in mind in the issue but I thought I'd share anyway😅

This is exactly what I had in mind, amazing! You are a hero. 🙇 🥇

I added a few more examples, including one with websockets and server side SVG generation which I found quite fun and maybe useful to someone 😄
I think there are lot more features that I didn't explore yet but these basic attributes seem already enough to do some interesting things.

Fantastic work @JPonte! Apologies for the delay getting around to this PR.

I really don't have any feedback on the work. I've tried it, it works brilliantly, I love Love LOVE the game of life demo! 😍

Being as I am, not an HTMX expert 😋, I think the best thing to do is just put it out there and await feedback.

I'll hit the approve button, my only question to you is: Are you happy? Do you think it's good as a first cut? Anything else you want to do to it?

[davesmith00000]

Love it. 😁

[JPonte]

Yes, I think I'm happy as it is right now.

I hope to actually use it myself soon in more personal projects. I really liked remaining fully on the server side for the whole stack 😀

Maybe I'll have something else to add later but for now, I think it's a good start.
