org: Fix drawer & block

- drawer entries without value were printed as FOO rather than :FOO:
- account for differences between raw & non-raw block:
  raw blocks are not wrapped in a further element, just raw text & line breaks:
  -> the first line has to be indented manually
  non raw blocks do not end in a linebreak newline -> the END_BLOCK line has to
  be indented (rather they end with a manual newline from another element)
