Drop unnecessary parenthesis in types, put in by the user
We were putting in parenthesis were the user did. Let's remove this since it just clutters up the types. The types are readable anyway since we print parens around infix operators and do not rely on fixity levels. When doing this I discovered that we were relying on user parenthesis when printin types like (a `O` b) c. This patchs fixes this problem so that parenthesis are always inserted around an infix op application in case it is applied to further arguments, or if it's an arguments to a type constructor. Tests are updated.
