Rework uniqTypes without duplication (#1316)

* Rework uniqTypes without  duplication

* Extra info for vX -> v7 conversion

* Add vX to naming

* Rework unwrap return

* Ignore gathering unique for v0

* Fix getUniq for V0 (well, def. throw-away, but anyway...)

* compareMap cleanup

* Cleanup author extraction

* Add modules via Struct.with (Metadata)

* Revert "Add modules via Struct.with (Metadata)"

This reverts commit 0666c3014cf840fb4ab26a5231cdf67dbe977bd7.

* Consistency in injected vs defined classes (Metadata)

* Add isTrue/isFalse to Bool

* Meta PlainType/MapType in registry

* Fix wrong v6 imports

* Extract storage modifier

* Split additional Metadata classes into interfaces

* Minor cleanups in type naming

* Static json renames

* Convert most V0 classes to interfaces

* Additional meta classes to interfaces

* No classes for Metadata V0 & V1 anymore

* Rename json imports

* Base cleanups

* Add polkadot static
