#36: CglTwomir generates invalid cuts

Component: CglTwomir | Version: release 0.5.1

------------------------+---------------------------------------------------
In determining whether a row is bounded, the DGG_getData function uses a
fixed value of DBL_MAX rather than the OsiSolverInterface object's
getInfinity() value. This resulted in invalid cuts with
OsiCpxSolverInterfacel. This bug may affect other Cgl generators as well.
