LEO-II's "--sos" option confusingly disables rather than enables SOS, and SOS seems to be ignored anyway; also, pass a number of facts that's more appropriate for each prover

eta-reduce definition-like equations for THF provers; Satallax in particular seems to love that

get rid of "conj_sym_kind" -- most interesting provers now have built-in sorts, and for the others (e.g. E) "Hypothesis" isn't too bad a default

extend ATP data structure to avoid having to perform ((non-)capture avoiding) beta reduction -- fixes a bug in the THF translation of "is_measure.simps"
