iOSKit Updated to Version 1.6

I have just updated iOSKit to version 1.6. This new version restores compatibility of the example project with the new Xojo release. The the example project now works in Xojo 2016r2+ and maintains backwards compatibility if you are still using an older version of Xojo. New classes are also added for UIDevice, NSUUID, and an extension for iOSTable to get an event when the table is scrolled to the bottom. Also added are various missing properties and a couple of new Extension methods. As always please let me know if you have any questions or requests.
