add more tests and fixes for command inheritance

- fix CommandType.__repr__
- secop/modules.py: command properties are allowed to be configured:
  - section 2: remove comment and rename
  - section 3: all accessible properties should be checked
- command description should be inherited also when taken from docstring
- move test for command inheritance to test_modules.py
- added tests to check for valid properties of commands
