//---------------------------------------------------------------------------------------
// This requires explaining
//
// The main app event loop sends events using libevent to wake up the dialog thread.
// The dialog thread is executing the event_base_loop. In this thread, application dialog
// boxes apps are started.
// Those dialogs connect to the event_base_loop via TCP/IP. The loop then responds to 
// network xml coded events and in it's turn sends SDL_user_events to the main app SDLevent
// handling.
// (the first idea was to get rid of QT in the main app, but the dialogs use FLTK now)
// The main app then catches the SDL user events and as instance will save the score or load
// or disable the card wich started the dialog box.
//
// Note that this thread only does message sorting and asynchronous data dispatching.
// All the shit is done in the main app.
