Redesign the "Rich Text" support in Forms
"Rich Text" property in Forms is not what it was meant in QTextEdit.
- "Rich Text" is the Qt's "acceptRichText". Change user name to "Accept Rich Text".
- Add a "richText" property [bool] and set user name to "Rich Text". If false, ensure plain text is always used.
- Add user name for a new "markdown" property
- Add a custom user-visible "plainText" property that forces plain text
"autoFormatting" - still keep it hidden.
