Create splash-screen to apps

[LuanRoger]

Motivation

On Xbox, when enter in a app or game, a splash-screen is brevely showned.

Implementation

Not every app have a splash-screen by default, just the games, so is considered to automatcly create for system apps.

Remarks

In the future is internaly planed to create a kind of API to anyone create apps for the launcher, but this idea is in validation.
In this is issue is related with the fact that each app on the planed API will implement a splash-screen.
