Improve presentation of old issig tactics

I found a way to build issig tactics which are two orders of magnitude
faster than the very old ones (which did not adjointify), but which keep
all do not adjust the sections and retractions.  The key is to apply
symmetry, so that we destruct a record rather than a sigma type.
However, the adjointifying versions are still an order of magnitude or
two faster than these versions, so we use the adjointifying ones by
default.

Port UnivalenceImpliesFunext

This closes #46.  Unfortunately, the typeclass glue won't work very
well until we migrate to the polyproj branch of HoTT/coq, because
typeclass resolution currently doesn't take into account universe
inconsistencies, so we'd need to explicitly provide two instances of
univalence to this theorem in order to use it.
Prove that the precategory of sets is a category
Fix the implicit arguments to [point]

Now it takes the type as an argument, rather than taking no arguments.
For bonus points, figure out how [point A] used to work.
Move some things out of Misc, add hProp lemmas

We now have better support for paths of hProps
trunc_hProp -> isset_hProp, deduplicate it

This closes #366

Merge pull request #362 from JasonGross/set-category-univalent

Set category is univalent
Use NaiveFunext for proving funext_downward_closed

The new version of universe polymorphism isn't as libral with inductive
universes.  So we use NaiveFunext to allow a simpler transformation of
universes.
Fixups to work with the latest polyproj branch.
Progress on adapting HoTT and categories to latest polyproj branch.
Progress on adapting HoTT and categories to latest polyproj branch.
Adapt categories and hit's code to latest polyproj (Private keyword).
- A few places raise universe inconsistencies in Categories still, not sure why.
- Some minor unification problems with apply/eauto discovered as well.
- Some places requiring more instances of Funext, as I expected.
Everything compiles quickly here.
