Fix bug#5475 : File Open Dialog

[renu.rajput at tcs.com]

Bugzilla Bug 5475
Control isnt transferred in the function CFileDialog::OnFolderChange()
incase of Customized file open dialog

Bug Description
The problem is this: CFileDialog has a built in function called
OnFolderChange, that is used to determine whether the user has changed
folders in the dialog, whether by double click or what not.. the program
i'm working on overrides the CFileDialog class, and includes more code for
the OnFolderChange function (and for other functions) for its own purposes.
the new OnFolderChange function works perfectly fine in windows, but is
completely ignored when using wine - it never even gets called, while the
rest of the dialog window retains all of its intended functionality.

ChangeLog
Send the CDN_FOLDERCHANGE message when browsing a folder.

Test case
Same exe as uploaded with the bug description is attached herewith.

Following patch generated against Wine version 0.9.18 in file:
