This fixes a few documentation issues I noticed.
- Explain what Func is supposed to return.
- Remove change reference to ActualNamespace to mention StructNamespace
instead.
- Remove references to Validatable, which no longer exists.
- Fix godoc formatting.
- Delete extra text from ReportValidationErrors comment.
- Change ReportError interface definition so its arguments are named
consistently with what they do.
Running goimports on the codebase deletes all the imports of "github.com/go-playground/universal-translator".
The fix consists of explicitly qualifying the import statements with ut.
