Title: fully qualify the Version class to prevent load-errors

We use paper_trail inside engines and this causes load-errors because Rails will load the wrong file for the `Version` class. The exact error is:

```
LoadError:
Expected /project/lib/equis_nennsystem/version.rb to define Project::Version
```

I patched paper_trail to fully qualify the constant name `"::Version"` this should have no effect on existing applications but fixed the problem for me.
