title: set default imageorient for TCEFORM
body: <p>I want to set the default imageorient of a TCEFORM.
  Standard value is 17 but I want to use 18.</p>
  
  <p>So I tried like mentioned here <a href="https://forge.typo3.org/issues/16676" rel="nofollow">https://forge.typo3.org/issues/16676</a> 
  this two methods in my PageTsConfig.ts:</p>
  
  <pre><code>TCEFORM.tt_content.imageorient.default = 18
  TCAdefaults.tt_content.imageorient = 18
  </code></pre>
  
  <p>and</p>
  
  <pre><code>mod.wizards.newContentElement.wizardItems.common.elements.image.tt_content_defValues.imageorient = 18
  mod.wizards.newContentElement.wizardItems.common.elements.textpic.tt_content_defValues.imageorient = 18
  </code></pre>
  
  <p>but neither the one nor the other is working.</p>
  
  <p>Any hints how I can achieve this?</p>
