Access Violation in SHBrowseForFolder

[woschwot at onlinehome.de]

Subject: Access Violation in SHBrowseForFolder
Description: It's not documented in MSDN but SHBrowseForFolder supports
             lpBrowseInfo->pszDisplayName = NULL. In this case Wine
             currently responds with an access violation when pressing
             OK in the Shell Browse Folder. The patch avoids this.
ChangeLog: In SHBrowseForFolder support lpBrowseInfo->pszDisplayName to 
be NULL
