Remove old ToggleSwitch and replace with UWP like ToggleSwitch

[punker76]

Remove old ToggleSwitch and ToggleSwitchButton class and create UWP like ToggleSwitch.

• Simplify ToggleSwitch (remove the old one incl. the ToggleSwitchButton)
• Use some additional properties from the old one
• No indeterminate state (use IsOn/IsChecked property with bool instead bool?)
  Why?

Hi @punker76 ,
is it possible to implement an indeterminate state to this control, so we can bind to bool?. see #3527

Thank you and happy coding,
Tim

@timunie No, I will not implement this here for this ToggleSwitch. IMO a ToggleSwitch should not have this behavior. If you need this, then this is the wrong control.

Hi Jan,
thank you for the feedback. I get your point, but in my special use case I have to let the user do a choice. So I will maybe stick with a custom control which does what I need, or switch to another control if I find one.
