Invisible Ownerdrawn buttons

[Arnaud ANDRE <aandr@info.fundp.ac.be>]

Changelog :
   wine/controls/button.c : get hbrush from WM_LCOLORBTN and is drawn grey
                                          by default

A very ridiculous patch but at least it fixes Bugzilla #54. The 
WM_LCOLORBTN isn't very useful but it's still the normal windows 
behaviour. Going back to see if i can do another tasklet...
