cutealien 91cb559caa Bugfix: FPS camera animator on X11 no longer tries grabbing mouse events.
Basically behavior about that is back to how it was in Irrlicht 1.8 - not perfect, but useable.
So window still jumps a bit when dragging toolbar, but no longer outside the sreen. And it's possible again to alt+tab to other windows.
The problem was caused by a combination of FPS camera changes and that we stopped doing mouse-coordinate clipping in the Linux device in r5593.
Basically that clipping had the side-effect that the fps-camera never considered a mouse "outside" on Linux.
Now on Linux we only update after we get a mouse-event (which we still get when the mouse is outside the window).
On Windows we still grab the mouse in the camera, thought that's likely _not_ the best way to do that. Windows has some mouse-grabbing support, 
and I suppose we could use that (or camera should check if that is used as it also can be set by users I think). So maybe in future this can be further improved.
Other operating systems (OSX) should behave like in 1.8 I hope, but as usual I can't test.

Also did a few minor cleanups in the camera.
- Back to using animateNode time instead of real-time. That's because that was not causing the problems I thought back then it might cause as time is only used for keyboard input and not mouse input.
- Moved updating CursorPos to the rest of the code checking CursorControl

Note: A future improvement would be to add support for systems without CursorControl object (could still use mouse-events to get it working usually).
