#11: Add loglevel control to Osi

 As of v 0.95, there is no direct loglevel control in Osi. Indirectly, one
 can use passInMessageHandler, but this typically has limited effect, since
 each solver has its own message handling mechanism in addition to Osi's.
 Instead, this ticket proposes two enhancements:

 1) make passInMessageHandler virtual, so that solver-specific actions can
 be taken when the Osi message handler is replaced.

 2) add virtual set/get logLevel(int) methods, which would provide a
 sufficiently general high-level control of messaging. What the actual int
 ''means'' should be left up to the solver.
