Changes for Screen saver And implement

Browse source 
1. Time value can be changes use SPI_SETSCREENSAVETIMEOUT to set the new value, current insate value are set to 30sec
2. SPI_GETSCREENSAVETIMEOUT Get the screen saver timeout value.
3. Dectect if screen saver is running with SPI_GETSCREENSAVERRUNNING
4. Set the state of screen saver with  SPI_SETSCREENSAVERRUNNING <- this is internal api see msdn 
 
Implement for mouse
1. SPI_GETWHEELSCROLLLINES I am but unsure if win32k need more changes it seam like it is only a counter that should be set/get a value and user apps take care of the rest. Implement it for jimtabor did request it. 
2. SPI_GETWHEELSCROLLCHARS  I am but unsure if win32k need more changes it seam like it is only a counter that should be set/get a value and user apps take care of the rest.
