Profpatsch fa71407f36 lib/generators: introduce a sane default for mkValueString
So far, `mkValueString` defaulted to `toString`,
which is a bad match for most configuration file formats,
especially because how booleans are formatted.
This also improves error messages for unsupported types.

Add a test to codify the formatting.
