Support for resolving reactive declarations

[josdejong]

Thanks for building this Webstorm plugin Tomasz! It works quite nicely.

It would be great if the plugin would also be able to resolve reactive declarations since this is such a core element of Svelte. I'm not sure if this is what is already discussed in #4. Currently Webstorm says "Unresolved variable or type ".

Here the code (straight from the Svelte tutorial https://svelte.dev/tutorial/reactive-declarations):

<script>
  let count = 0;
  $: doubled = count * 2;

  function handleClick() {
    count += 1;
  }
</script>

<button on:click={handleClick}>
  Clicked {count} {count === 1 ? 'time' : 'times'}
</button>

<p>{count} doubled is {doubled}</p>

I know I know. This is core feature but it's really tricky to pull of because it changes core semantics of JS.

97 is a work in progress support of this but is blocked by #100... and updates to WebStorm.

Also, duplicate of #7

👍 I can indeed imagine that this is tricky to pull off, I hope that it will work out!
