MinMaxLinearEquationSolver: Added a flag 'hasNoEndComponent' that is true if the system is known to have no end components. This decides if policy iteration does require a valid initial scheduler.
Renamed the 'hasNoEndComponents' solver requirement to 'hasUniqueSolution' as this is the actual thing we require for, e.g. sound value iteration.

GurobiLpSolver: Improved interface by
* adding settings MIPFocus (to switch between solving strategies) and ConcurrentMIP (to spawn multiple MIP solvers)
* allowing to set the desired and get the achieved gap between lower- and upper bound when solving MIP models
* retrieving other solutions found during optimization.
