Load RTTI information and use it for fetching files

[ShadelessFox]

Decima Engine uses RTTI that represents type information at runtime. There are hundreds of different objects for which we don't want to write wrappers. Instead, we can use RTTI information to reconstruct object hierarchy for reading, writing, pretty-printing, and displaying these objects.

But we should be aware of internal objects that are not exposed via RTTI.
