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.

style(hott): rename instances of pType using pfoo instead of Foo
...
For example, the pointed suspension operation was called Susp before this commit, but now is called psusp

feat(init.path): update init.path to use tactics, also some additions
...
Now the file hardly uses eq.rec explicitly anymore.
Also add the fact that horizontal and vertical inverses of paths are equal
Make one more argument explicit in eq.cancel_left and eq.cancel_right (to make it nicer to write 'apply cancel_right p')

feat(library/tactic): make let tactic transparent, introduce new opaque note tactic
...
The new let tactic is semantically equivalent to let terms, while `note`
preserves its old opaque behavior.
