[Proposal] Making JME more artist friendly

@MonkeyGroove

It could be some logo or splash screen , purely optionnal, no one is forced to use it, but having some JME3 splashcreen or small JME3 logo among other technology logos in some page at the game start, i htink this would be the best way to promote and says the game was made with JME3.

Working on it : JME splash screen
