BootstrAPI 0.8.0

This is a BREAKING release. Since BootstrAPI is still in a early development stage, I allow myself to make breaking changes in minor versions. The REST API has changed as described in #104 and documented in #108

What's Changed

• Change over from collection models to use of array schema by @pathob in #104
• Replace faulty asciidoc documentation by markdown by @pathob in #108
• Dozens of dependency improvements and updates by @pathob and @renovate

Full Changelog: v0.7.1...v0.8.0
