Improvement Description

Commit 6871d1c pushed a lot of module-related logging to higher verbose levels, which now makes it impossible to visually differentiate the hierarchy of any of these messages at a quick glance.

To improve this, unique verbose prefixes are now added for all levels, rather than using prefix 4 for levels 4 through 10. This allows for the same visual differentiation as before, as well as in all other cases for messages of different levels.
