Print RootMoveList startup scoring

This satisfies a specific user request of 28/8/2009

"The only issue I have is that during multiPV analysis, the depth 1
best move score is not reported by the engine (reporting for the best
move begins at depth 2).  I need it at depth 1 also. Would it be
possible to make this modification in future versions? This would be
of great help as otherwise I will have to use a lesser engine.

The goal of my project is to calculate the ELO performance in a game
and also the ELO rating of individual moves. For this I need depth 1
scores for lower rated performances. I intend to distribute the program
for free upon completion.

Thanks, Jack Welbourne"
