'forall' always a keyword, plus the dot type operator
This merge request:
- implements the "Make
foralla keyword in types" proposal (accepted) - implements the "The dot type operator" proposal (accepted)
- fixes a bad error message about existential quantification, Trac #16311
It also improves handling of Unicode syntax in hintExplicitForall and adds two related utilities, starSym and forallSym.
