Add an "Undo" button - window got stuck "Fullscreenized"

[seanmcnally98]

Had a piece of software I used fullscreenizer on which made it totally stuck in "fullscreenized" mode. Even a reinstall of that software didn't fix it. Would be great if there was a way to set it back to normal. In the meantime, for anyone googling how to undo a fullscreenize of a window, I used this autohotkey script:

`::
tog := (!tog)
If (tog)
	WinSet, Style, -0xC10000, A
Else
	WinSet, Style, +0xC10000, A
return

The tilde ` key will set any active window back to nornal.
