Refactor script definitions and resolving/refining infrastructure:

- implement wrappers to wrap old and new API providers and resolvers
- make old API deprecated (with error where possible)
- drop old internal classes related to the old API
- refactor usages accordingly
- fix and add missing features to the scripting API where necessary
