title: How to paste plain text in a Quill-based editor
body: <p>Quill (<a href="https://quilljs.com/" rel="noreferrer">https://quilljs.com/</a>) makes it simple to embed a quality text editor in a web page. When pasting html content in the editor, it filters the pasted html and then puts it into the text editor. My question is: How can I configure Quill so it pastes only plain text in the text editor? It would filter out all tags and leave the plain text only.</p>
  
  <p>The documentation about the Clipboard module (<a href="http://quilljs.com/docs/modules/clipboard/" rel="noreferrer">http://quilljs.com/docs/modules/clipboard/</a>) says that it is possible to add custom Matchers to the Clipboard, that will kind of filter the pasted text.</p>
  
  <p>I don't know how to write a matcher that only allows plain text. Any help and any examples are much appreciated - thanks!</p>
