Draft: move the convertDraftTexts function to make_text

The old `convertDraftTexts` function was moved from the `Draft.py`
module to the `draftutils.utils` module; however, here it is
not possible to use because the `makeText` function
is not accessible. Therefore, the function is moved to
`draftmake.make_text`.
