Fixed zoom window bar not draggable (issue 114)

Checked for all other uses of "while (!Get_input())", seems ok.
Palette screen: Copy,Swap,X-Swap now take place when you click button, not release.
In all screens where you could press ` and pick a color (palette, shade...): The action now takes place when you click, not release.
