Subject: [PATCH] Fixed header-based authorization.

Previous to this update, when I tried to do API-key authorization using
headers rather than the query string, Swagger-UI would not send my
authorization headers. This update basically makes the authorization
options get set AFTER Swagger-UI has finished initializing, which seems
to make the system much happier. Changes based on a conversation on a
mostly-unrelated pull request,
