Updated to use the new ReadAnyGroup instead of the old readAny function. Some tests are still hanging or failing (mostly due to shutdown issues)

It inherits two functions from its two base classes. Explicitly use the
one from ApplicationBase.

use a different work around for the thread_local problem: moving the code using the thread_local specifier to the cc file also solved the problem and does not require a complicated work around using a map...

necessary changes for the latest DeviceAccess update (readAsync() return type no longer a reference, and other related changes)

Changed an exception into an assert, since the function is only internally used and the exception is never thrown. Clafiried the documentation about this.

removed incorrect implementation of operator[] and operator() in ApplicationModule (and use the implementations of ModuleImpl instead)

refactored a type if-then-else monster into a for_each loop and exlcuded a pure cout function from the converage report

fixed bug that using poll-type transfers in testable mode could sometimes lead to stalled tests or assert failures.

- clarified some comments

added move-assignment operators for the accessors, which is required to use move-assignment operators of modules containing accessors

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.

fix running into an assertion sometimes: getQualitifedName() should also be possible if the highest hierarchy is a Module (e.g. a VirtualModule)

Make Module::connectTo() no longer a template, since a virtual function can anyway not be overridden with a different return type... (c.f. the comment in the deleted code)

- removed the no-longer-necessary optional argument of findTag() - use flatten() instead

refactor ArrayAccessor and ScalarAccessor: split off common code and put into common base class InversionOfControlAccessor

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
