zEmbedded.load() can accept an HTMLElement as a parameter

User Story

As a dev, I want to embed multiple zul files on a page for all div with a specific class.
For example, I plan to embed multiple zul in multiple Divs on a page. Each div looks like:

<div class="component-demo" data-path="mydemo.zul"/>

To give an ID to those Div is unnecessary.

Acceptance Criteria

a javascript function like zEmbedded.load() that accepts HTMLElement as a parameter.
