doc: Move the class description to be just below the brief description

- Drop the "Brief description" header as it became redundant
  with this change.
- Fix a bug in the editor help where an extraneous newline was added
  after the header if the class isn't inherited by any others.
- Remove the Category line in the rST markup as it's not useful
  for API users.
