Meik Sievertsen 9988679d56 - streamlined reports to consist of the feature set we decided upon (Nils, your turn now) 
- use getenv instead of $_ENV (with $_ENV the case could be wrong)
- permission fixes (there was a bug arising with getting permission flags - re-added them and handled roles deletion differently)
- implemented max login attempts
- changed the expected return parameters for logins/sessions
- added acp page for editing report/denial reasons
- other fixes here and there
