Clarified details in spec_initialValuePropagation and fixed wrong reference in exceptionHandlingDesign

  - lower case commands
  - place test executables in top-level build directory

fix not using a ConsumingFanOut when connecting the two poll-types each with a push-type variable (e.g. control system)

this happens frequently when following the modern connectTo() logic and connecting everything with the control system.

- The direction cannot be determined from the accessor which is being decorated
- Fixed wrong usage of feeding/consuming in Applicaton::createDeviceVariable. Was used consistently wrong, so there was no behaviour bug. But the code was confusing because the direction was wrong.

Tests still failing.

- All accessors come up in exception state.
- Read-accessors increase counter in init phase

Assertion is gone, but tests still failing

- Basically half of the spec deviates from the current implementation now.
