[Scip] Transformed constraints

[waniek@zib.de]

If you use the SCIP-Binary provided on the SCIP-Homepage (or use the
ZIBoptSuite in default configuration), the ZIMPL-Support is already
included and you can read your ZIMPL-file directly into SCIP.

Alternatively you can just call "zimpl <yourfile>" (e.g. in a command
line) and it transforms your ZIMPL-File into an LP-File.

> same folder as SCIP (I'm in Windows 7). How can I make SCIP now that
> it should use ZIMPL?
