[Coin-lpsolver] SBB Infeasibility (part 2)

[Lou Hafer]

Jean-Sebastien,

	The correct test should be !status_ && bestObjective_>=1.0e30. (Ref.
John's posting of Mar. 16th). At a glance over the most recent revisions of
SbbModel.cpp, looks like this may have gotten lost in the recent server
problems.
