Update Drop and Tether typings

This is a breaking change that simplifies the definition files
and exports the right thing for the external modules.
Previously, the external module export was wrong
(the global `Drop` and `Tether` constructors are exported
when these libraries are imported in CommonJS, not the
namespaces as the typings suggested).
