saugns v0.3.8. Clean-up redesign. Fix timing bugs. Most commits near the top, after the renaming to 'saugns', have been replaced by expanded commits a bit further down. Superficial stylistic changes have been rolled back a bit, while the valuable redesign parts have been streamlined in redone versions. To make space for expanding list syntax, undocumented '' usage with few effects as a generic subscope is renamed to '<>'. The latter could be given a real semantics later on. Furthermore, the parser has been simplified with a new round of changes and default time durations in scripts debugged. The design now looks a bit more like 2020-06 "mgensys", in part. Next up, preparing to expand language features on a cleaner ground. Changes the fix for -r 1 hangs. Now data is generated, and this extreme case also tested within the interpreter code.
