new monotonicity theorems

new theorem zmult_eq_0_iff

renamed sort "numeral" to "number"

simplified the <= monotonicity proof

local qeds: print rule;

added show_hyps flag;

local qed; print rule;

term/prop: include number; method args: exlude method meta chars;

added show_hyps flag; local qed: print rule;

export assumption_tac; local qeds: print rule; same_tac: actually insert rules, !! bind vars;

removed merge_theories;

removed metacuts_tac;

tmp_path: *add* path;

thms_containing: undeclared consts error;

removed pretty_thm_no_hyps (again);

removed merge_theories;

may get BASH_PATH etc. from env;

new theorems for the "at most" relation

Symtab.lookup_multi;

more specific exn;
