Adding more DB groups to test suits

Introduce evaluation of an environment variable to choose if all, only database or only database unit tests are to be executed.
This is mainly required on automated execution on Jenkins

A TestCase which is not annotated to be in group DB will not allow access to the database connection.
This is necessary to categorize unit test and avoid duplicate test case execution - it also allows us to closely review unit test implementations to identify unnecessary db calls.

Revert "Dont bother with stream_resolve_include_path if the path is already absolute"

Fix some PHPDocs

Some classes included via `use` did not even exist anymore.

In case the update server may deliver malicious content this would allow an adversary to inject arbitrary HTML into the response. So very bad stuff.
