Here a totally superfluously patch:
a splash screen which shows up while loading LyX. ;)
I've added a parameter which enlarges the time the splash
screen is shown.
Maybe someone has a nice idea for a splash screen picture.
We could also print text on it, something like this
"This is LyX 1.5 alpha! You will die if you rely."
