Starting up emulationstation takes me about 1 minute over the network
with a large collection of 27 systems with images.
This patch uses the loading screen to tell the user about the status
of the startup, with information how many systems are left for view
initialization.
The most beefy part of the startup process is initializing the views,
and preloading images.
This patch extends the `renderLoadingScreen` function to take a string
and uses it in `ViewController::preload`.
v2: Add SplashScreenProgress option enabled by default.
* Split out UIMode controller in separate class (in es-app).
