[MiNT] WM_REPOSED implementation

[Olivier Landemarre <olivier.landemarre@utbm.fr>]

Hello all

I'm quite surprising of the implementation in XAAES of new message 
WM_REPOSED, I think WM_REPOSED is a very good way to change position and 
size in same time, and I totaly agree with this, because change position 
then change size is some time not very beautifull on screen. But I'm 
quite surprising, that this message is send only if application have 
done a wind_set(WF_OPTS) so for all windows that need support this, this 
is a general message, and more simple for application should to use 
shel_write(SWM_NEWMSG,wisgr,...) with wisgr  with bit 1 to 1 if 
WM_REPOSED is support, I 'm going to add this in myaes.

Regards

Olivier
