Allow disabling transfer rate logging per input/output (optional, default is on).

This commit introduces new property to FairMQDevice to control whether rateLogger thread should print rates for a given input/output.
Per default logging is enabled, so existing code works as before and does not need to be updated.
To turn off logging for an initialized input/output, set the `LogInputRate`/`LogOutputRate` property to `0`.

Example:
``` c++
splitter.ChangeState(FairMQSplitter::INIT);
// turn off rate logging for input 1 and output 4
splitter.SetProperty(FairMQSplitter::LogInputRate, 0, 1);
splitter.SetProperty(FairMQSplitter::LogOutputRate, 0, 4);
```
rename the Detector.h in dbase to FairDBDetector.h
Add missing files
Fix typo in filename. Due to the typo the files wasn't found and the build process crashes.
Fix tests. Add parameter which passes the transport engine to the tests. Before all digi and reco tests run always with Geant3, also the tests which are named TGeant4.
bugfix: handling empty _linux_flavour variable if lsb_release is not installed
bugfix: incorrect buffer size config

Migration of MC classes for multi-threading:
- RootManager and Logger not yet ported
Load library explicitely, since the library TutFairDbMQ contain partly the same classes as libFairTestDetector. This results in problems when using rootmap files. The problem has to be correctly fixed in Tutorial6 by renaming the classes.
start introducing namespaces to FairRoot
 Introducing namespaces to FairRoot 2
 Introducing namespaces to FairRoot 3
revert changes in FairDB and remove the examples from the compliation for now
Namespaces cleaning
Namespaces for FairRoot 4
Finally working with namespaces
Add the examples and adapt to the namespaces, still need to solve problem with T3 and T6 thez are commited out for now.
continue with namespaces and adapt Tutorial 1
