EstimateS 9.10 debug output

Following up from bug 37252, when EstimateS 9.10 is launched, the main window
should show an embedded about dialog (the same dialog that would be displayed
by selecting Help -> About). However, with wine-11.0-rc3, no dialog appears,
and only a small rectangle with its perimeter colored differently from the main
window background can be seen. Selecting various menu options that should
result in an embedded dialog being displayed has no effect.

On Windows 10, the about embedded dialog is displayed on startup, and selecting
the various menu options does trigger the display of an appropriate dialog.

As the reporter of bug 37252 did not mention any problems with the application
after working around the original issue with native riched20, I confirmed (with
native riched20) in a Ubuntu 14.04.6 environment that dialogs are properly
displayed with wine-1.7.25 and stopped displaying correctly with wine-2.0.

Regression testing identified the following commit:

4277b055dec37fb8da85d6b674e9b522c8bdbfd6 is the first bad commit
commit 4277b055dec37fb8da85d6b674e9b522c8bdbfd6

Reverting the corresponding affected lines in dlls/win32u/window.c on top of
wine-11.0-rc3 allows the application (with builtin riched20) to display dialogs
correctly once more.
