Message:

Modified ObserverLog: Singleton and both output to screen and internal Log.

• ObserverLog can now either be printed concurrently or later requested as string (e.g. on exit as has been done before). This should ease debugging Observer code.
• enable/disableLogging() (dis)activate printing to screen.
• ObserverLog is now a true singleton.

Details:

• Implemented helper class ObserverLog::Log which is returned as boost::shared_ptr on addMessage() and can be streamed to.
• On dstor the logged message is appended with endl, placed into ObserverLog's internal log and printed on screen if enableLogging().
• NOTE: streaming std::endl is not working, and not necessary.
