title: Get current brick ID in twig template?
body: <p>Currently I am creating custom bricks - sample:</p>
  
  <pre><code>{% set store = [] %}    
  {% for i in 1..20 %}
     {% set store = store|merge([(i*8) ~ "px"]) %}
  {% endfor %}
  
  {% set heightSel = pimcore_select('heightSel', {
      store: store,
      reload: true,
      width: 100
  }) %}
  
  {% if editmode %}
      &lt;div class="container editprop-container no-material"&gt;
          &lt;div class="ed-col ed-col-100"&gt;
              &lt;label&gt;{{ "Height"|trans }}&lt;/label&gt;&lt;br/&gt;
              {{ heightSel|raw }}
          &lt;/div&gt;
      &lt;/div&gt;
  {% endif %}
  
  &lt;div class="spacer spacer-{{ heightSel.getData()|default("0px") }}"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>Because I want to put the editing options (<code>.editprop-container</code>) into a custom modal I need some unique ID for this brick (such that it does not conflict with other bricks). Is there some possiblity to the the brick ID? </p>
  
  <p>Note: A twig extension would be valid solution, but this does not help me because I do not know how to retrieve some custom ID of an editable anyway.</p>
