- forbidden names and forbidden base names are case **insensitive**
so we need to check all lowercase here.
- add test that config value is also read case insensitive.

This allows to configure forbidden filenames (the full filename like `.htaccess`)
and also forbidden basenames like `com0` where `com0`, `com0.txt` and `com0.tar.gz` will match.
We need this as only using basenames was too restrictive and will cause problems on some systems when updating.
