Set mousewheel behavior to zoom or scroll with Performance recordings

Open Settings and set the new Flamechart mouse wheel action setting to change how mousewheels behave on the Performance panel.

For example, when you use a mousewheel on the Main section of a recording, or when you swipe with two fingers on a trackpad, the default behavior is to zoom in or out. When you change the setting to Scroll, this gesture now scrolls up or down.
