Johannes Schickel 463e475bd6 SCI: Save mouse position in SciEvent.
Instead of querying the event manager for the current mouse cursor coordinates
kGetEvent now uses the saved mouse positions, which will assure every event
will be processed with the correct coordinates instead of the current ones.
Various other functions using SciEvent directly were adapted too.

This fixes cursor click positions for the WinCE backend.

Thanks to wjp and waltervn for helping me with this.
