David Jennes #964

The Swift 4 templates are now deprecated. This means we will no longer test if the generated output is valid Swift code. We will still try to keep these up-to-date with context changes.
David Jennes #955
Our spacing & trimming "hack" is now considered deprecated, and in the next major version we'll switch to Stencil's new "smart" trimming behaviour (see Stencil documentation for more information). Our built-in templates have already switched to this modern behaviour, you can try it with your own templates by using the --experimental-modern-spacing flag.
