1. changed configuration variables for linear programming (Cplex_tools):
LP_SOLVER is either CPLEX or GLPK
CPLEX_PATH is the path to the cplex binary
GLPK_PATH is the path to the glpk binary
The change makes it possible to switch between glpk and cplex at runtime.
2. moved conflicting list theories out of Library.thy into ROOT.ML
