Request to add "rv_backgroundCheckColor"

[trietbui85]

I want to use FlycoRoundView to add a "selected" state for the Checkable control (CheckBox, Switch...) but it seems doesn't support.
Could you add support for attribute "rv_backgroundCheckColor"?

EDIT: it would be perfect if we also have "rv_textCheckColor".

Thank you.
