A try at allowing matching on applications as a binary syntax node by default.
It breaks tauto as [?X _ _] matches much more terms. It is mostly fixed
by not destructing objects of record types. The new [intuition] was also
pulling an unneeded dependency in Field_theory which can be cleared
easily. Zis_gcd_bezout is also considered a conjunction now, which seems
correct(?).
