mod: Ext 15 — disjunctive (:any) conditions, 333/333

(:any (list c1 c2 ...)) compiles to Prolog disjunction (g1 ; g2 ; ...), completing
the condition boolean algebra (AND via :when list, :not, :any). cond->goal
recurses so combinators nest arbitrarily; the proof tree shows the compiled
disjunction verbatim. Maps onto Prolog's control constructs rather than
reimplementing boolean logic in SX. +10 tests.
