Move the soft inequalities directly into the solver.
- Clean up.

Cleanup the constraint solver a bit and fix a bug when a variable is removed.

Don't copy the constraint list, just use a pointer to the list.
There was a strange crash under gcc4. After some searching I found out that there is some clash with namespaces.
After removing the namespaces it works again. Could somebody explain what went wrong there?

Add an alternative solver to lp_solve. The solver based on Ingo's active set solver but is able to handle arbitrary hard and soft constraints. The advantage to lp_solve is that the active set solver can optimize variable in respect to a quadratic objective function. This makes it possible to minimise the quadratic derivation to a desired value e.g. \Sum_i(x_i - x_{i,pref})^2 -> min.
The solver part has been refactored in this way that both solver can be used with the same layout specifications. The active set solver is default now; the performance is not as good as lp_solve, though.
