This patch separates Swagger-specifications and the minifySwagger.pl from other
api-files by moving specifications & minifier into api/v1/swagger.

We have been using the Swagger2.0-driven REST API on Mojolicious for 1 year now
in production and I am certain we have a pretty good idea on how to work with
the limitations of Swagger2.0
We participated in the development of the Mojolicious::Plugin::Swagger and know
it well. We have made an extension to the plugin to provide full CORS support
and have been building all our in-house features on the new REST API.
