Add rex_valueChanged to UISwitch

[dmcrodrigues]

Motivation

I've used a few switches in the last days and I found very useful establishing an action to act immediately upon the change of the switch but also controlling the enabled state automatically.

Description

I created this new property highly inspired in the implementation of rex_pressed and everything worked as expected. However, there's an issue since iOS 7 where a switch can trigger multiple notifications of value changed even when there's not a change of switch's state, rdar://14485185. I changed the implementation a bit to adopt internal observation of changes and trigger the action manually only when there's in fact a change to achieve the originally expected behaviour.

I'm not happy with this but the issue is real and undesirable so I decided to contribute it because probably this may be useful to others facing this particular problem.

In case of positive feedback, I'll try to invest some time in a way to test it since apparently we cannot manually trigger .ValueChanged events for controls beyond UIButton.

I'm not happy with this and I think there might be some problems with it so I'll close this.
