I'm still not sure if my "solution" to the event system really works under  
any circumstances. It needs extensive testing.

However, the replacement of SetEventObject should assure that the sources can  
compile against this version of ParaGUI without any changes. I'm not sure if  
it's a good idea to keep the old functions and mark them as deprecated. This  
still allows other users to use this function. When they switch to a new  
compiler or compiler version, it may cause exceptions in their application.

The function PG_RegisterEventHandlerObj is - AFAIK - barely used directly. So  
there is probably no need to break the binary compatibility at this point.  
Instead its implementation can be changed to throw an exception if it is used  
and a new function - maybe called PG_RegisterEventHandlerObjEx or something  
like that - can be invented.

As I previously wrote, it might be very useful to use libsigc++ instead of a  
self-built event handler (signal/slot) system because it's a solid-proven  
library.
