Add new dll mscat32

[Vijay Kiran Kamuju]

Hi,

I would like to add a stub dll for mscat32.dll in wine.
It mostly is a forwarder dll ie, it has forwards for most of the
functions to wintrust.dll
And it also provides functions for reading catalog files.
It is mostly used by microsoft for it installers.
I mean for its own products like Winodows Media Player 9, IE, etc.
I wanted to inform to get the approval from wine team, for inclusion
of this dll.

Thanks,
VJ
