Patch for wheel mouse support

[Guillaume Laurent <glaurent worldnet fr>]

The following patch enables scrollbar to be moved with the mouse
wheel (applies against gtk+ 1.1.1, should apply against 1.0.5 too) :

The only problem is that it requires the user to move the mouse over a
scrollbar. I'm looking for an elegant way to achieve the same effect
while on scrolled windows, suggestions welcome.
