feat(hott/library): various changes and additions.
...
Most notably:
Give le.refl the attribute [refl]. This simplifies tactic proofs in various places.
Redefine the order of trunc_index, and instantiate it as weak order.
Add more about pointed equivalences.

refactor(library/algebra/complete_lattice): make complete lattices more usable
...
I addressed two problems. First, the theorem names and notation were all in
the namespace complete_lattice. The problem was that if you opened that
namespace, names (like "sup" and "inf") and notation clashed with global notation
for lattices.
The other problem was that if you defined a lattice using Sup, the Sup you got
was not the Sup you want; it was the Sup-construction from the Inf-construction
from the Sup.
Everything seems good now.

Adds weak_order, lattice and complete_lattice instances for Prop, fun, and set. Adds supporting
theorems to various other places.

refactor(library): use type classes for encoding all arithmetic operations
...
Before this commit we were using overloading for concrete structures and
type classes for abstract ones.
This is the first of series of commits that implement this modification
