[osg-submissions] Plugin DLL search order fix for Win32

[Luigi Calori]

Hi Robert, Just for curiosity, did you get my previous mail with patch 
attached? I did not received from the list but apparently Eric did...
That is really puzzling.
If you do not have recevived the patch, I can resend.

Anyway, my previous patch managed to NOT renaming the .lib but only the 
.dll This should not have impact on Find and other stuff.
The .dll are searched at runtime and, probably theyr name is written 
inside .lib, so there are chances that nothing has to be changed.
I do not have run a lot of test though, just VPB under VS7.1
I can test the whole stuff unde VS8 today.

Le me know.
Luigi
