[Scip] how to get dual solutions in Soplex

[Ambros Gleixner]

Hi Xiangyong,

until now, the command line version of SoPlex did not output the dual
values.  I have quickly written a patch, which is attached, and
hopefully contains no bugs.. :).
You have to copy soplexmain.cpp into the SoPlex "src" directory and
recompile.  We will include this also in the next SoPlex release.
