MSW: Fix for wxComboBox::SetEditable

[Nusret Taşçı]

I'm not sure whether this is the right way to propose a small patch like 
this. I tried to propose another patch with SourceForge, but it looks 
like everyone is very busy and is afraid of looking at proposed patches.
However...
Currently wxComboBox::SetEditable() isn't implemented for MSW.
I propose following patch.

<   // Can't implement in MSW?
< //  HWND hWnd = GetHwnd();
< //  SendMessage(hWnd, EM_SETREADONLY, (WPARAM)!editable, (LPARAM)0L);
