XWA, Exit confirm dialog is shown twice

[JeremyAnsel]

When you close the window, the confirm dialog is shown twice.

How to reproduce the issue:

• open YOGEME.exe v1.2.5
• select XWA Platform
• close the window
• click Yes

While closing the form, after confirm exit it calls Application.Exit() which in turn executes the form close again. Fixed for the next upload, XvT and TIE also repaired.

Issue appears to apply to XWA only, even though shut down code is same among all three platforms
