fix scheme and versioning

Swagger basePath was breaking on https

Also, the version set on the restify server was not being passed through (apparently the property name is server*s*)

```coffeescript
pkg = require './package'

module.exports.server = server = restify.createServer
    name: pkg.name
    version: pkg.version

restifySwagger.configure server # versioning breaks without ,{version: pkg.version}
```
