[Qt-interest] Qt 4.5.0 and manifest files

[Marco Borm]

Hi Pascal,

I don't know if there is a better solution but I'm sure you don't need 
multiple copies of the crt-dll.
Changing the "file name="msvcr90d.dll"" in the manifest to something 
like "..\..\msvcr90d.dll" should be possible, we used the same workaround.
