Ptyhon: Detect internal modules and do not list them in errors
Currently, internal modules are listed under errors because their version is not specified. This behaviour should be avoided, since they belong to the checked program.
The output looks like this:
#### errors
##### Python
**tellus**
* version not specified
**test_ashfall**
* version not specified
**test_basics**
* version not specified
