reintroduce this idea of running "metisFT" after a failed "metis" -- I took it out in e85ce10cef1a because I couldn't think of a reasonable use case, but now that ATPs use sound encodings and include dangerous facts (e.g. True_or_False) it makes more sense than ever to run "metisFT" after "metis"

beware of polymorphic types in typed translation symbol declarations -- match alpha-equivalent types and, more importantly, prevent unsoundnesses by generating type constraints on the arguments of a polymorphic symbols (otherwise "hAPP" can be given any result type)

minor doc fixes
2011-05-01, by blanchet

2011-05-01, by blanchet
cleanup proxification/unproxification and make sure that "num_atp_type_args" is called on the proxy in the reconstruction code, since "c_fequal" has one type arg but the unproxified equal has 0

make sure that fequal keeps its type arguments for mangled type systems
2011-05-01, by blanchet
no needless "fequal" proxies if "explicit_apply" is set + always have readable names
