Add Debug options to AdapterManager

[laeubi]

Today I needed to debug a nasty problem why Adaption did not returned the desired result.
I ended up with the need of checkout the code and modify the AdapterManager class because it is nearly impossible to debug in the current form to find out why an adaption does not work.

Especially if one needs to debug a complex application it can easily become a nightmare, I therefore think we should have a debug option / flag that allows to be enabled an print information what kind of adaption is taken and why it probably has failed /e.g no matching factory, incompatible classes, ...
