[TIMOB-3479] Selecting a row in TiUITableView causes rows at regular intervals to also be selected (allowsSelection)

When allowsSelection = true on a TiUITableView and there are more rows than can be displayed on the screen, selecting a row causes rows at repeated intervals offscreen to also be selected.

An example is attached.

The problem is that a cell's state isn't being properly reset when it is reused, hence when the selected cell goes offscreen it becomes available for reuse resulting in the next drawn cell to be selected.

I believe the cause of this is actually the TiUITableViewCell incorrectly overriding setSelected:.

In TiUITableView.m setSelected: doesn't call the corresponding method on super:

-(void)setSelected:(BOOL)yn
{
    [super setHighlighted:yn];
    [self updateGradientLayer:yn|[self isHighlighted]];
}

it should be changed to:

-(void)setSelected:(BOOL)yn
{
    [super setSelected:yn];
    [super setHighlighted:yn];
    [self updateGradientLayer:yn|[self isHighlighted]];
}

which fixes the problem.
