[PATCH v2] kernel32: Use setprogname(3) to set the program name if available.

[Theodore Dubois]

I CC’d him on the original email. 

It would be neat if the wine program name could show up in Activity Monitor on OSX, so I can tell one wine process apart from another. There is a way to do it (http://stackoverflow.com/questions/4217947/setting-process-name-on-mac-os-x-at-runtime) but it requires undocumented APIs. (Damn.)
