Acceptance criteria

• New option in developer settings
  • (default) When enabled, rich text formatting menu is available and markdown is disabled
  • When disabled, rich text formatting menu is not available and markdown is enabled
• When markdown is enabled (i.e. rich text formatting setting is disabled):
  • Plain text and markdown can be entered into the composer
  • The send button is enabled accordingly
  • Reply mode works
  • Editing a message works
    • When editing a message, the composer is populated with the plain text body of the original message
  • The message can be send and the formatting from the markdown is rendered correctly and message content sent is correctly formatted.
• Under the hood, the editor is always the Matrix Rich Text Editor (as opposed to a basic text field)
