- add new api function "aa_section" to allow structuring of larger test cases
- generalize login during tests further. When "user_info" is provided
it can be used to either login via login credentials or directly
via user_id (next step: integrate config-option for test users, this
will allow pure web tests to run against a different server)
- extend regression test to cover new features
- bump version numbers to 5.10.0d7
