Allow user to set WM_CLASS via his environment

Hi,

The name of the executable is currently used as the WM_CLASS set by winex11.drv
however this doesn't work reliably in cases where the executable name is the
same, e.g. I have a few windows games on my system where the executable is
simply named "game.exe", leading to one game being associated with another's
icon in GNOME's running applications panel.

I can get around this problem by using a symlink but that approach isn't ideal
- in the case I tried I also had to create a symlink for another directory
located in the directory where the exe was located.

I've enclosed a patch that allows the user to specify WINEWMCLASS in his
environment and have wine use that value as an alternative to the default
behaviour.

Let me know what you think.

Thanks
