Refactor handling of parens in types (#874)
* Fix type parenthesization in Hoogle backend
Ported the logic in the HTML and LaTeX backends for adding in parens
into something top-level in 'GhcUtil'. Calling that from the Hoogle
backend fixes #873.
* Remove parenthesizing logic from LaTeX and XHTML backends
Now, the only times that parenthesis in types are added in any backend
is through the explicit 'HsParTy' constructor. Precedence is also
represented as its own datatype.
* List out cases explicitly vs. catch-all
* Fix printing of parens for QuantifiedConstraints
The priority of printing 'forall' types was just one too high.
Fixes #877.
* Accept HTML output for quantified contexts test
