Forgot to adpopt test to the new method signature.

* Fix initial msg. Add automatic connection to the LoggingModule.

Now the Logger is a VariableGroup and in the prepare() method an empty
msg is written once. This makes sure the LoggingModule is not waiting
for initial values of Loggers and messages by other Loggers get lost.

* Add message in case on modules with Logger are found.

* Fix test and remove implementation of removed method.

* Do not use hard coded tags but use default tags.

Now all tags given to the LoggingModule are used to look for senders.

If a header-only library requires linking a 3rd party library, the ..._LIBRARIES variable could not be used in depending projects, because it
contained NOTFOUND.

This needs to be done here since the recent changes in DeviceAccess, see comment for reason.

CircularDependencyDetector: Avoid deadlock in registerDependencyWait

If a circular dependency was checked and the dependent module was not
yet in the waitMap, the lock was never released.

Print path to the nonvirtual module if oneLevelUp or oneUpAndHide are
detected directly below the applicaiton root.

The user can now also choose to publish messages only to the control
system.

Removed libtine linking workaround from FindDOOCS. Doocs libraries now are themselves linked correctly against tine.
