Refactor Object metadata

Browse source 
* API kept the same (Although functions could be renamed to set_metadata/get_metadata in a later PR), so not much should change.
* Metadata now exposed as individual properties.
* Properties are editable in inspector (unless metadata name begins with _) under the metadata/ namespace.
* Added the ability to Add/Remove metadata properties to the inspector.

This is a functionality that was requested very often, that makes metadata work a bit more similar to custom properties in Blender.
