Capture CEGUI output

[rgrieder]

In CEGUI, there is a possibility to manipulate the output (log). Normally, everything is written to CEGUI.log, but by deriving from CEGUI::Logger and creating an instance of that before initialising the system, you can capture the output. See CEGUILogger.h
By looking at CEGUI.log I can see that all usual output has the level "std", but it's quite much (175 lines for a simple main menu).
I suggest deriving from CEGUI::DefaultLogger and override logEvent, but make the base class call as first function statement (DefaultLogger::logEvent). The output is then written to CEGUI.log like now, but you can route everything with a higher priority than std to our own output stream too (COUT). That should make error tracking easier when programming the GUI.

I have written code that instantiates the DefaultLogger before the CEGUI System in order to specify another log file (and directory).

Implemented as suggested.
