Also removed some admissible instances:

- `Atomic s (ResolveProph (Val v1) (Val v2))` (this one was already admissible)
- `Atomic s Skip` (became admissible due to the instance for β)

Let `iProp` refer to `uPred ... : Type` instead of `uPredO ... : ofeT`

Reorder Requires so that we do not depend of Export bugs.

See merge request iris/iris!313

The general idea is to first import/export modules which are further
than the current one, and then import/export modules which are close
dependencies.

This commit tries to use the same order of imports for every file, and
describes the convention in ProofGuide.md. There is one exception,
where we do not follow said convention: in program_logic/weakestpre.v,
using that order would break printing of texan triples (??).

Add `iStopProof` tactic

Closes #265

We have these instances for all other logical operations too to support
