[sdk/kdesrc-build/docbook_historied_per_file] doc: Eliminate distinction between `prefix` and `install-dir`

Git commit 3d5459c7177e61a10e243789922e0dc885b45e98 by Andrew Shark.

Pushed by ashark into branch 'docbook_historied_per_file'.

Eliminate distinction between `prefix` and `install-dir`

We will not use `--prefix` cli option or `prefix` config option anymore, because it means same thing what `install-dir` was meant for.

- For those who used '$MODULE' or '${MODULE}' in the `prefix` config option, we now will make that substitution in `install-dir` config option.
- Add a warning message if the prefix config option still found in user config

Closes #141
