[Cbc] Message printing with CbcSolver

[Lou Hafer]

Kish,

	There's a logLevel command which will cause cbc to pump out additional 
information. This now works again --- trunk r1607 contains the (trivial) fix to 
CbcSolver.cpp. The relevant point is that COIN_HAS_CBC must be defined before 
the include of CbcOrClpParam.hpp. (Used to be automatic; no longer, due to 
changes in the build system.) It's three lines, easy to install in whatever 
version of the code you're using.

	See if this helps.
