New function read_cterms is a combination of read_def_cterm and
read_cterm. It reads and simultaneously type-checks a list of strings.
cterm_of no longer catches exception TYPE; instead it must be caught later on
and a message printed using Sign.exn_type_msg. More informative messages can
be printed this way.

Improved comments.

infer_types now takes a term list and a type list as argument. It
is defined using the new function infer_terms. Error messages and
comments also improved.
