* Fix issues identified with the Hapi 17 update
This commit introduces a variety of changes, primarily fixes, but it
also collapses the typings into a single file. Collapsing it into a
single file means simpler augmentation of types, which is common in
Hapi.
Thank you to SimonSchick for contributing a number of changes here.
* fix response property
These weak type errors were not caught in TS 2.4 RC. The final TS 2.4
will catch weak type errors with primitives, so this PR fixes those
now-caught errors.
