Add synopsis so make build-dep does not complain

Nitpick, yes, but I've seen the complaint enough times today to bother.

That complaint is only useful to maintainers, and it's even in color.

```
[WARNING] Failed checks on coq-iris-builddep package definition from source at file:///Users/pgiarrusso/git/Coq/0IRIS-SWITCH/iris/build-dep:
    error 57: Synopsis and description must not be both empty
```

This proof also more easily scales to other recursive types, like
trees etc.

Notably, `big_andL_andL` and `big_andL_and` where a ⊣⊢ and ⊢ version
of the same lemma. I favored the `big_opL_op` naming scheme.

Allow multiple arguments in `iEval .. in` and `iSimpl in`.

Closes #238
