Added new device ids for better compatibility. Remove hardcoded variables allowing userspace (plist) settings to apply. Painstakingly optimized default settings to provide the best possible experience. Improve pointer motion calculation, mode switching,… etc. Lots of code cleanups, refactoring. Clean up the IOLog.
