Fixes from Dmitry Yakimov: fixed bugs 159 and 160: + added threaded timers support ! fixed restoring sdl window focus (AV in windows message handler) ! disabled forgotten cdrom and joystick in config file. * disabled minimizing sdl window while loosing focus. PocketPC does not have a task bar, so it is an inconvenient and unusual behaviour for PPC users. + added WIN_Paint handler for GAPI ! fixed loosing focus while using GAPI videi driver + added TestTimer project * removed unnecessary macros (ENABLE_WINDIB ...) from projects
