Resolve: #296 Hide url box when going fullscreen

Resolve: #296
On current-window.js added to the array EVENTS: “enter-full-screen”, “leave-full-screen”.

On script.js added the events that detect entering and leaving the full screen and toggle the nav class ‘hidden’. Also it resizes the view.
currentWindow.on('enter-full-screen', () => {
if (!rawFrame) nav.classList.toggle('hidden', true)
webview.emitResize()
})
currentWindow.on('leave-full-screen', () => {
if (!rawFrame) nav.classList.toggle('hidden', false)
webview.emitResize()
})

On windows.js added the listeners for the events:
this.window.on('enter-full-screen', () => {
this.send('enter-full-screen')
})
this.window.on('leave-full-screen', () => {
this.send('leave-full-screen')
})

This is perfect, thank you! I'll include it in the next release.

Glad this also fixes the resizing issue when exiting fullscreen for youtube and the such.
