Implement better completions

I think a Visitor is a bit of an overkill for this. You can use Tree.find_pred() or even Tree.iter_subtrees() instead.

Can you help with getting the document's source? Looking at the other ones, I think it's

get_locals_for(ls.workspace.get_document(params.textDocument.uri)).source

instead, right?

So,

return [
    definition[0] if not definition[0][0] =="!" else definition[0][1:]
    for definition in
    lark_grammar.lark_grammar_parser.parse(doc).find_pred(lambda node: node.rule in {"rule", "token"})
]

(yes, I love one-liners)

What's the thing with CompletionItem right here?

Maybe @rmcgregor1990 can answer these.
