HolSatLib refactoring and additions. * MiniSat-p v1.14 added as a "built-in" SAT-solver * A new function SAT_TAUT_PROVE uses MiniSat to prove propositional tautologies within HOL * HolSatLib refactored into satTools and dimacsTools * Local documentation removed; it was folded into the Description some time ago. * The HolSatLib interface remains the same, save for the addition of SAT_TAUT_PROVE. * Two minor additions to defCNF: a global ref for the variable name prefix used by DEF_CNF_VECTOR_CONV (defaulting to the current setting), and a global ref for the number of new vars introduced by definitional CNF.
