bugfix [#21173] Autocompleate raises an error

Browse Source 
split PropertyRNA off into 3 types, base type, collection and array, since array and collections needed internal checks inside almost every function its better to have the, as subclassed to the property type. This makes introspection more useful.

Also made printing of structs and properties prettier giveing type and length.
