Palette managing patch.

[kenon at go2.pl]

Hello

I'm not enough familiar with wine/windows internals ,so I want someone 
to check my patch before comitting to CVS.

Changelog:

Maciek Kaliszewski <kenon at go2.pl>

* dlls/ttydrv/palette.c, dlls/ttydrv/dc.c, dlls/ttydrv/ttydrv.h,
graphics/x11drv/palette.c, graphics/x11drv/init.c, objects/palette.c,
objects/color.c, windows/painting.c, include/palette.h, 
include/x11drv.h

Sending WM_PALETTECHANGED message when it is really needed.
