[Cbc] Message printing with CbcSolver

[Kish Shen]

Hi John and Stefan,

Thanks for your help and explanation of the issue. I have managed to get 
CBC to produce messages with the changes you suggested.

One minor issue -- in the print out of the messages, the Id for the 
message, seen in the standalone cbc solver, i.e.

Cbc0038I Pass   1: suminf.    0.66204 (6) obj. 228065 iterations 86
^^^^^^^^

is not printed when running with CbcMain1, but they are printed when I 
run Clp (i.e. solving linear problems), I use the same message handler 
there.

Does it make sense to set the log level for Cgl and Coin to 0? I guess 
that means if they print messages at every linear solve? If not, do 
printing them add any useful information?

Thanks and cheers,

Kish
