uses new splash screen. Screen does not need modification anymore for each

new minor release. Version is printed over it and taken from the ROOT_RELEASE
define. All core developers are credited. When called as "root -a" the credit
text scrolls and shows names of all people in CREDITS file. The "About ROOT..."
menu items in the Help menus of TCanvas, TBrowser and TTreeViewer call
"root -a &" and show the scrolling credits. To close splash screen click
with mouse in it. Not yet tested on display with < 255 colors so some tuning
might be needed for these old enviroments.
