Flick Stick fixed duration to 0.1 seconds

Browse source 
Formerly, there were "6 frames" with a precalculated change factor on each frame.
This allowed to use Flick Stick exclusively on vsync 60 Hz screens only (6 *
16.6 ms = 100 ms). By using any other refresh rate, or just disabling vsync,
these 6 frames could take any time, normally much less than the intended 100 ms.
Now delta time is used to calculate the angle change on each frame displayed,
so the entire flick duration remains at 100 ms, independent of refresh rate.
