Merge branch 'nclose_subseteq' into 'master'

Use notation N @⊆ E to avoid ambiguity.

Since `nclose : namespace → coPset` is declared as a coercion, the notation `nclose N ⊆ E` was pretty printed as `N ⊆ E`. However, `N ⊆ E` could not be typechecked because type checking goes from left to right, and as such would look for an instance `SubsetEq namespace`, which causes the right hand side to be ill-typed.
