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

Ordering is now: first by number of assumptions, second by the substitution size.
Treat elim/dest rules like erule/drule would:
* "elim" is now a subset of "dest" and matches on conclusion of goal and
major premise against any premise of goal. Computed substitution size
takes both into account.
* "dest" no longer has a restriction that limits its conclusion to a var.
