- Exception handling decorator and ThreadedFanOut send condition variable notificatios via the DeviceModule
- FanOut sends terminate to impl and all slaves.
Solves (some?) shutdown issues, but breaks bi-directional array test.

supposedly fixed implementation, but tests are conceptually broken and/or implementation cannot be terminated

first implementation of device initialisation handler. Simple test passes, but needs to be extended.

implemented first interface change in DeviceModule to support initialisationHandlers. Test in place but failing due to missing implementation.

moved exception handling documentation into its own dox file and added documentation about DataValidity flag propagation

changed: device is not intialized in constructor anymore.

Test still does not work.
-Unable to get the exception status for the device throwing exception.
-Second device only works it has it's own trigger.

- add test for full exception handling

  DeviceModule and ControlSystemModule now do not take the optional prefix argument in their constructors any more. Use the [] operator instead to get the submodule.

- Add ExceptionHandlingDecorator and decorate all device variables with it.

- added more comments
- need to catch exception by reference, else the message seems to be lost
- test if the message is correct
- test if device is really closed and opened again
- changed names of status variables in control system to match the general naming conventions

Proper implementation of move constructors and move assignment operators for all module types (including tests for the assignment operator)

fixed connectTo() so it now uses the dynamic/virtual model and thus obeys e.g. eliminated hierarchies etc.

Fixed some more problems with the move sematics of EntityOwner/Module. Re-registration at the owner was missing and some things were done in the wrong place. Also the move assignment is now back again.

put the move constructor and move assignment-operator into the EntitiOwner base-class and inherit them
