Bug: Instance of 'Save as:' dialog not using the Qt replacement enabled by `-winecompat`

[VortexParadox]

Describe the bug

Trying to close a document without saving will trigger Hammer to ask if the user wants to save or discard the current changes to a map. If one chooses to save, it will open the save dialog, but even when using -winecompat, the dialog is not drawn with Qt.

To Reproduce

1. Start Hammer with -winecompat.
2. Open a new map.
3. Draw a block or place any entity, just to cause the document to become dirty.
4. Try closing the document, and choose Save when asked.
5. The 'Save as:' dialog will be using Wine's awful dialog, instead of the Qt one used in other instances of the 'Save as:' window.

Issue Map

N/A

Expected Behavior

All instances of the 'Save as:' dialog should be using the more approachable Qt versions when running under -winecompat.
