UI performance tweaks

Due to low specs on tv boxes, some changes are there to be taken in consideration to improve the "responsiveness" of the app.

No Css Transformations

This is used to remove css transformations for the player to be "snappier".

No Controls Gradient Background

This is used to remove controls gradient background.

UI Delay

This is used to set the delay for the UI to show.

Web TV React

const diva = new createDivaWebTV (el, {
    // other props
    noTransitions: false,
    noControlsGradientBackground: false,
    uiDelay: 5000,
    // other props
})

Web TV Vanilla

const App = () => (
    <DivaWebTV
        // ...
        noTransitions={false}
        noControlsGradientBackground={false}
        uiDelay={5000}
        // ...
    />
)
