TKController (iOS) v1.4.1

This is currently awaiting review by Apple prior to release. It contains a number of changes, primarily to fix a few UI glitches that are evident on iOS 8 and above.
I’ve also changed the banner source to Google, in line with the Android app, as Apple have discontinued their banner service. The banner revenue is vital for the app to continue at the moment as it needs to cover the cost of the web server that hosts this site and provides the device definitions to the app.
