title: labeling relationship lines in mysql workbench erd
body: <p>I'm not really sure if ERD is the proper term, but occasionally I see diagrams created where the line in between two entities is labeled with text to describe the relationship.</p>
  
  <p>For example if I had <code>User</code>, <code>Item</code>, <code>ItemRating</code>, I may want to describe the line between <code>User</code> and <code>ItemRating</code> as "rates" and the line between <code>Item</code> and <code>ItemRating</code> as "is rated by".</p>

  <p>I found I can make a text object in mysql workbench, and place it where I want, but I can't find a way to attach it to a line so that it moves with the line if I rearrange things.</p>
