WindowFinder overhaul

[FrigoCoder]

FrigoTab at the moment enumerates applications with EnumWindows, based on WindowExStyles.AppWindow, ToolWindow, and other flags.

Unfortunately this is inappropriate, the standard Alt-Tab and Win-Tab implementation behaves very differently. Raymond Chen wrote a blog entry about it: https://blogs.msdn.microsoft.com/oldnewthing/20071008-00/?p=24863

Several side effects arise as a result:

• IBM Notes breaks down to dozens of windows #19 IBM Notes breaks down to dozens of windows
• Visual Studio leaves a border in the background #17 Visual Studio leaves a border in the background
• EnumWindows does not list Metro apps in Windows 10 #15 EnumWindows does not list Metro apps in Windows 10
• Non-application windows appear on Windows 10 #14 Non-application windows appear on Windows 10
• Start menu appears as tool window #9 Start menu appears as tool window
• Toolbars with transparency and blur #5 Toolbars with transparency and blur
• GIMP toolbars #2 GIMP toolbars

Find out how do Alt-Tab and Win-Tab exactly work, and change my implementation to conform to them.

No Total Commander windows are showing up if I open the About dialog box. This clearly needs more work.
