Implicitly convert Pointer to id

[vakrilov]

Think about implicitly converting pointer to ids. This will make the following code easier to translate to NativeScript:

CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor whiteColor] CGColor], (id)[[UIColor blackColor] CGColor], nil];

Currently, this looks like this on NS:

var gradient = CAGradientLayer.layer();
var colorsArray = NSMutableArray.alloc().initWithCapacity(2);
colorsArray.addObject(interop.types.id(UIColor.redColor().CGColor));
colorsArray.addObject(interop.types.id(UIColor.blueColor().CGColor));
gradient.colors = colorsArray;

If there is implicit convertion - we can get rid of the interop.types.id( ... ) calls

This can now be done simply as:

var gradient = CAGradientLayer.layer();
gradient.colors = [UIColor.redColor().CGColor, UIColor.blueColor().CGColor];
