Implement room version capabilities in CS API (#866)

Browse Source 
* Add wiring for querying the roomserver for the default room version

* Try to implement /capabilities for room versions

* Update copyright notices

* Update sytests, add /capabilities endpoint into CS API

* Update sytest-whitelist

* Add GetDefaultRoomVersion

* Fix cases where state package was shadowed

* Fix version formatting

* Update Dockerfile to Go 1.13.6

* oh yes types I remember

* And fix the default too
