[Cbc] CBC with GMPL

[Ted Ralphs]

Yes, there is a specific version of Glpk that will work with each
version of Cbc. Check the script get.Glpk in the ThirdParty/Glpk for
the correct version number. The trunk version uses 4.45, so we seem to
be lagging behind the most recent version of GLPK quite a bit.

Cheers,

Ted
