Emmet support

Emmet is an editor plug-in for many IDEs / editors that supports quick generation of HTML. For example

section.break>h1+ul>li*5

expands to

<section class="break">
    <h1></h1>
    <ul>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
    </ul>
</section>

It would be very useful to have something like this in Eclipse as well.

I think we can check what is done in svelte-language-server. It basically use getEmmetCompletionParticipants from ‘vscode-emmet-helper’ inside the language server. See HTML plugin

I see Emmet can do some HTML or CSS templating, not sure LemMinX would like to get into the direction of being a LS for non-XML languages.
